Question

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

Answer 1

⇒208+(n−1)8=496.

⇒(n−1)8=288.

⇒n−1=36⇒n=37.

Hence, there are 37 integers between 200 and 500 which are divisible by 8.

Answer 2

Answer:

Step-by-step explanation:

The first term between 200 and 500 divisible by 8 is 208, and the last term is 496.

So, first term (a) = 208

Common difference (d) = 8

an=a+(n−1)d=496

⇒208+(n−1)8=496

⇒(n−1)8=288

⇒n−1=36⇒n=37

Hence, there are 37 integers between 200 and 500 which are divisible by 8.
