Answer:

ans is 100 please mark me as brainlest

Answer 2

Answer:

100

Step-by-step explanation:

For first ap:

a=a+d(n-1)

a100=a+d(100-1)

=a+99d

a1000=a+999d

For second ap:

a'=a'+d(n-1)

a'100=a'+99d

a'1000=a'+999d

Assuming a' is greater than a

(a'+99d)-(a+99d)=100

a'+99d-a-99d=100

a'-a=100. -1

Subtracting the thousandth terms of the ap:

(a'+999d)-(a+999d)

a'+999d-a-999d

a'-a=100. from -1
