Two A.P’s have the same common difference. The difference between their 100th  terms is `111 222 333.` What is the difference between their Millionth terms?

Text Solution

Verified by Experts

Let the common difference be 'd 'and the first terms of two A.Ps be `a_1 & a_2`
100th term it 1st A.P - 100th term of 2nd A.P `= 111222333`
`(a_1+99d)-(a_2+99d) = 111222333`
`a_1+99d-a_2-99d = 111222333`
