Which term of the series 5, 8, 11, 14, ....is 320 ?
Answer & Solution
Correct Answer:
Option
C
Clearly, 5 + 3 = 8, 8 + 3 = 11, 11 + 3 = 14,................
So, the series in an A.P. in which a = 5 and d = 3
Let 320 be the nth term of the series.
Then, 320 = 5 + (n - 1) × 3 or (n - 1) = 105 or n = 106
