Question

Given the arithmetic sequence an = −1 + 7(n − 1), what is the domain for n? All integers All integers where n ≥ 0 All integers where n ≥ 1 All integers where n > 1

Answer 1

here is an ap given
with 1st term = -1. and common difference is 7

in this series we can say that 1st term is -1 , 2nd term is 6 , 3rd term is 13 , and so on
therefore in a series we cannot define a 0th term , so here n will be greater than or equal to 1.
