Directions to Solve

Choose the correct alternative that will continue the same pattern and replace the question mark in the given series.


18.
Which term of the series 5, 8, 11, 14,.....is 320?
104th
105th
106th
64th
Answer: Option
Explanation:

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.
