Which term of the AP 9, 17, 25, … is 201?

Answer and explanation

Correct answer: 25वाँ

This is an nth-term and term-position problem in an arithmetic progression. The first term is a = 9, and the common difference is d = 17 − 9 = 8. Let 201 be the nth term. Using aₙ = a + (n − 1)d, we obtain 201 = 9 + 8(n − 1). Subtract 9 from both sides: 192 = 8(n − 1). Dividing by 8 gives n − 1 = 24, and therefore n = 25. Thus 201 is the 25th term, so option C is correct. The integer value confirms that 201 belongs to the progression. A useful check is that 24 increments of 8 added to the first term give 9 + 24 × 8 = 201. The nearby alternatives arise from counting increments as terms or taking one extra increment.
