Question

find the number of integers between 200 and 800 which are divisible by 6.

Answer 1

required integers are :-

204, 210, 216, ......., 792,798

This forms as AP, with,

First term, a = 204

Last term, l = 798

Common difference = 6

So,

l = a + (n+1)d

798 = 204 + 6(n-1)

6(n-1) = 594

n - 1 = 99

n = 100

Hence, the number of integers between 200 and 800 which are divisible by 6 are 100.
