Answer 2

Step-by-step explanation:

let assume something:-

first series's first term is a and it's common difference is d.

second series's first term is b and it's common difference is d (because both series common difference is same)

so 5th term of first series is = a+4d

so 5th Term of second series = b+ 4d

now :- b+ 4d -a- 4d = 1000.

:- b-a = 1000

now, 1000 terms of both series :-

a+999d

b+ 999d

so difference of 1000 th term is = b-a = 1000.

2) if common difference is negetive means ap will decrease.
