If 𝑎 = 3 a=3 and 𝑑 = 0 d=0, what is the 5th number in the arithmetic series?
Explanation
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
