Show Answer
Answer: Option A Explanation: Sum of first 12 terms is equal to sum of first 14 terms. Sum of first 14 terms = Sum of first 12 terms + 13th term + 14th term => 13th term + 14th term = 0 Let us assume 13th term = k, common ratio = r. 14th term will be kr. k + kr = 0 k (1 + r) = 0 => r = -1 as k cannot be zero Common ratio = -1. Now, if the first term of this GP is a, second term would be -a, third would be a and so on The GP would be a, -a, a, -a, a, -a,… Sum to even number of terms = 0 Sum to odd number of terms = a Sum to 17 terms is 92 => a = 92 Third term = a = 92
