Explanation
The December 2023 ceasefire in Yemen was facilitated by the United Nations. Part of the Yemeni civil war and the Iran –Saudi Arabia proxy conflict Date: 26 March 2015 – ongoing  (10 years and 2 months) Operation Decisive Storm  26 March – 21 April 2015  (3 weeks and 6 days) Operation Restoring Hope  22 April 2015 – present   (10 years, 1 month and 4 days)

Explanation
 The official motto of the Pakistan Army is "Iman, Taqwa, Jihad fi-Sabilillah" Translates to " Faith, Piety, Struggle in the Name of God ". This motto emphasizes the concept of "struggle" (Jihad) in the service of God.  Founded: 14 August 1947 Colours white and green Anniversaries: Defence Day: 6 September

Explanation
 "Who" is used as the subject of a clause referring to people. The clause "who wants a pen" describes "the one" — the person. "Whom" is used for objects of verbs or prepositions. "Whose" shows possession. "Which" refers to things, not people.

Explanation
A non-traditional security threat refers to issues that are not related to traditional military threats like war or invasion. Climate change is considered non-traditional Because it poses a significant threat to Pakistan's stability and security, But it's not a direct military threat like an invasion

Explanation
  Given:

Speed from A to B = 40 km/h

Speed from B to A = 40 km/h + 50% of 40 km/h = 40 + 20 = 60 km/h

Find:
Average speed for the whole journey (both ways).
Formula for average speed when distance is the same but speeds differ:
Average speed = 2 × Speed 1 × Speed 2 Speed 1 + Speed 2 text{Average speed} = frac{2 times text{Speed}_1 times text{Speed}_2}{text{Speed}_1 + text{Speed}_2} ​ ​
Plug in values:
= 2 × 40 × 60 40 + 60 = 4800 100 = 48  km/h = frac{2 times 40 times 60}{40 + 60} = frac{4800}{100} = 48 text{ km/h} = 2 × 40 × 60 ​ 40 + 60 = 4800 /100 = 48  km/h

Explanation
 The formula for the nth term of an arithmetic sequence is aₙ = a₁ + (n - 1)d, where:  aₙ is the nth term of the sequence a₁ is the first term of the sequence n is the term number (e.g., 1st term, 2nd term, etc.) d is the common difference between consecutive terms For example, if the first term (a₁) is 2 and the commo n difference (d) is 3, then the 5th term (a₅) would be calculated as follows:  a₅ = 2 + (5 - 1)3 = 2 + 4 * 3 = 2 + 12 = 14 

Explanation
If the common difference d = 0 d = 0 , the sequence is constant. General formula for an arithmetic sequence:
a n = a + ( n − 1 ) d a_n = a + (n - 1)d For d = 0 d = 0
a n = 3 + ( n − 1 ) × 0 = 3 a_n = 3 + (n - 1) times 0 = 3

So, the 5th number a 5 = 3 a_5 = 3

Explanation
This looks like an arithmetic sequence problem.
If the first term a = 3 a = 3 and last term l = 18 l = 18 , and there are 4 numbers in between , the total terms n = 6 (3 + 4 + 18). The terms:
a 1 = 3 a_1 = 3
a 6 = 18 a_6 = 18
Number of terms n = 6 n = 6 n = 6 Common difference d = 18 − 3 6 − 1 = 15 5 = 3 d = frac{18 - 3}{6 - 1} = frac{15}{5} = 3 d

The 3rd middle number is the 4th term :
a 4 = a 1 + 3 d = 3 + 3 × 3 = 12

Explanation
To solve the equation:
x 2 + 16 = 0 x^2 + 16 = 0 Step 1: Isolate x^2
x 2 = − 16 x^2 = -16 Step 2: Take the square root of both sides
x = ± − 16 x = pm sqrt{-16} Since − 16 sqrt{-16} − 1 involves the square root of a negative number, we use imaginary numbers :
x = ± 4 i x = pm 4i x = ± 4 i

Explanation
If the common difference d = 0 d = 0 , the sequence is constant. General formula for an arithmetic sequence:
a n = a + ( n − 1 ) d a_n = a + (n - 1)d For d = 0 d = 0
a n = 3 + ( n − 1 ) × 0 = 3 a_n = 3 + (n - 1) times 0 = 3

So, the 5th number a 5 = 3 a_5 = 3

Explanation
This looks like an arithmetic sequence problem.
If the first term a = 3 a = 3 and last term l = 18 l = 18 , and there are 4 numbers in between , the total terms n = 6 (3 + 4 + 18). The terms:
a 1 = 3 a_1 = 3
a 6 = 18 a_6 = 18
Number of terms n = 6 n = 6 n = 6 Common difference d = 18 − 3 6 − 1 = 15 5 = 3 d = frac{18 - 3}{6 - 1} = frac{15}{5} = 3 d

The 3rd middle number is the 4th term :
a 4 = a 1 + 3 d = 3 + 3 × 3 = 12

x 2 + 16 = 0 x^2 + 16 = 0 Step 1: Isolate x^2

If the common difference d = 0 d = 0 , the sequence is constant. General formula for an arithmetic sequence:
a n = a + ( n − 1 ) d a_n = a + (n - 1)d For d = 0 d = 0
a n = 3 + ( n − 1 ) × 0 = 3 a_n = 3 + (n - 1) times 0 = 3
