Question

Find the sum of the integers between 100 and 200 that are divisible by 2or 3 ?

Answer 1

Answer:

The sum of integers between 100 and 200 that are divisible by 6 is 2550.

Step-by-step explanation:

First no. between 100 and 200 that is  divisible by 6 is 102

The last no. between 100 and 200 that is  divisible by 6 is 198

Now the numbers between 100 and 200 that is  divisible by 6:

102,102+6,102+6+6 ,....

So, it forma an AP

a = first term = 102

d = common difference = 6

Formula of nth term =

Sum of n terms =

Substitute n =17

Hence the sum of integers between 100 and 200 that are divisible by 6 is 2550
