200, 208, 216,.......... 496
a = 200
d = 8
L = 496
=> a + (n-1)d = 496
=> 200 + (n-1) 8 = 496
=> (n-1) 8 = 296
=> n-1 = 37
=> n = 38
Required number of terms = 38

well brother it is told in question that divisible by 8 between 200 to 500 not from 200 to 500
the lower limit is counted
Here the lower limit is 200
so we count
but the answer is 37
