Which term of the series 5, 8, 11, 14,.....is 320?
A. 104th
B. 105th
C. 106th
D. 64th
Answer: Option C
Solution (By Examveda Team)
Clearly, 5 + 3 = 8, 8 + 3 = 11, 11 + 3 = 14, .....So, the series is an A.P. in which a - 5 and d = 3.
Let 320 be the nth term of the series.
Then, 320 = 5 + (n - 1) x 3 or (n - 1) = 105 or n = 106.
