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).
