An arithmetic progression has an odd number of terms. The sum of its first and last terms is equal to twice which term?

Answer and explanation

Correct answer: मध्य पद

In an AP with an odd number of terms, the middle term is the arithmetic mean of the first and last terms. Hence, first term + last term = 2 × middle term. Exam tip: first check whether the number of terms is odd.
