The integers between 200 and 500 which are divisible by 8 are 208, 216, 224, ....... , 496.
 
The given series in an A.P since d = 8.
Here, a = 208, d = 8 and an = 496
 
an = a + (n - 1)d
→ 496    = 208 + (n - 1)8
→ 8n - 8 = 288
→ 8n      = 296
→   n      = 37
 
 
→ There are 37 integers between 200 and 500 that are divisible by 8.
