Answer 1

Explanation:

let Frist term of one AP be = a

common difference = d

let Frist term of second AP be = b

common difference = d ( comm. diff is same )

now

n th term of Frist AP An = a + (n-1)d .....(1)

nth term of second AP Bn = b + (n-1)d ....(2)

subtract equation (2) from (1)

An - Bn = {a+ (n-1)d }- {b +(n-1)d}

An-Bn = a + (n-1)d - b - (n-1) d

An - Bn = a-b

it means difference of nth term is equal to difference of first term

now it is given A100 - B100 = 111222333

so a-b = 111222333

we need to find

A(million) - B (million) = a-b

A(million) - B (million) = 111222333.

( a- b = 111222333)
