Question

find how many integers between 200 and 500 are divisible by 8.​

Answer 1

Answer:

Answer

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

Answer 2

Answer:

37

Step-by-step explanation:

Solution:-

Numbers divisible by 8 between 200 and 500 are 208, 216, 224,...496.

Let these be "n" in numbers.

So, 496 = 208 + (n - 1) × 8

=> 62 = 26 + ( n - 1 )

=> n - 1 = 62 - 26 = 36

=> n = 36 + 1 = 37

Hence, there are 37 such integers.
