Answer:

159

numbers betwewn 2222 to 3333 are divisible by 7

Step-by-step explanation:

First no divisible by 7  between 2222 to 3333 is 2226

So the  no will be

2226,2233,.....

when we divide by 7 the remainder=1

so the last no=3333-1=3332

Hence an Ap is FORMED where

a=2226,d=7,an=3332, N=?

we KNOW that

an=a+(n-1)7

3332=2226+(n-1)7

7(n-1)=3332-2226

=1106

n-1=1106/7=158

n=158+1

=159
