What will be the 35th term of the AP −17, −15/2, 2, ...?

Answer and explanation

Correct answer: 306

First calculate the common difference from consecutive terms. We have d = −15/2 − (−17) = −15/2 + 34/2 = 19/2. Checking the next pair gives 2 − (−15/2) = 4/2 + 15/2 = 19/2, so the progression is consistent. For an AP, aₙ = a₁ + (n − 1)d. Therefore a₃₅ = −17 + (35 − 1)(19/2) = −17 + 34 × 19/2 = −17 + 17 × 19 = −17 + 323 = 306. Hence option C is correct. The values 272, 276 and 284 do not satisfy the standard nth-term calculation. Including 306 as option C corrects the incomplete original option set and makes the answer unique.
