Answer 2

The common difference is 7

Step-by-step explanation:

Formula of nth term in AP : $a_n=a+(n-1)d$

$a_n$ = nth term

a= first term

n = no. of term

d= common term

Substitute n = 11

$a_{11}=a+(11-1)d=38$---1

Substitute n= 16

$a_{16}=a+(16-1)d=73$ ---2

Subtract 2 from 1

$a+(16-1)d-[a+(11-1)d]=73-38\\a+15d-a-10d=35\\5d=35\\d=7$

Hence The common difference is 7
