Expert Answer:

The common difference of two AP's is same, i.e d = d'

T'100 = a'+ (100-1) d'

T100 = a + (100-1) d

T'100 - T100 = 100 = a'+ (100-1) d' - (a + (100-1) d)

                        100  = a' - a                        [Since d =d']

So the difference between their 1000th term is

T'1000 - T1000 = a'+ (1000-1) d' - (a + (1000-1) d) = a' + 999 d'  - a - 999d = a' - a   = 100
