Question

answer it step by step please please​

Answer 1

Given:-

$a=10\\a_2=7\\l=-62$

What we need to find:-

eleventh term from the last

Process:-

Step 1:-

$d=a_2-a=7-10=-3$

Step 2:-

$a_n$ (from last) $=l-(n-1)d$

                    $=-62-(11-1)(-3)\\=-62+30\\=-32$

∴ -32 is eleventh term from last term in the arithmetic progression.
