# Chapter 10 - Section 10.2 - Arithmetic Sequences - Exercise Set - Page 1059: 24

General equation is: $a_n=2+5(n-1)$; $97$

#### Work Step by Step

Formula to calculate the nth term of an arithmetic sequence is: $a_n=a_1+d(n-1)$ Here, $a_1:$ First term and $d=$ common difference Since, we have $a_1=2$ Then, our General equation is: $a_n=2+5(n-1)$ $a_{20}=2+5(20-1)=2+95=97$
