In an arithmetic progression (a,a+d,a+2d,\ldots), which is the second term?

Answer and explanation

Correct answer: a+d

In an arithmetic progression, the first term is a and the common difference d is added to obtain each successive term. Thus, in the sequence a, a+d, a+2d, ..., the second term is a+d. The expression a+2d represents the third term, not the second. Exam tip: remember the first few terms as a, a+d, a+2d, ... to identify the required term quickly.
