In following number series, two terms have been put within brackets. Choose the appropriate option - How many terms are there in the series 201, 208, 215, ..., 369 ?

Answer: C. 25

(Use Arithmetic Progression)

The given series is an A.P. in which a = 201 and d = 7.
Let the number of terms be n.
Then, 369 = 201 + (n - 1) x 7 or  n = 25.
Hence, the answer is (c).
