Two APs have the same common difference. The difference between their `100^(t h)`terms is 100, what is the difference between their `1000^(t h)`terms?

Explanation

`S_1:a_1,a_2.....d`

`S_2:b_1,b_2.....l`

`a_100-b_100=100`

`a_100=a+(100-1)d`

`=a+99d`

`b_100=b+(100-1)l`

`=b+99l`

`a_100-b_100=100`
