Question

find the sum of all numbers between 60 and 600 which are divisible by 8​

Answer 1

Answer:

The first number is 64 & the last number is 592 both of which are divisible by 8 and are between 60 to 600.

Tn = a + (n - 1)*d

592 = 64 + (n - 1)*8

592 - 64 = 8n - 8

528 + 8 = 8n

8n = 536

n = 536 / 8

n = 67

There are 67 positive integers between 60 to 600 which are divisible by 8.
