242580

Step-by-step explanation:

Given : Positive integers from 5 to 1555 inclusive

To Find :Find the sum of all positive integers, from 5 to 1555 inclusive, that are divisible by 5

Solution:

All positive integers, from 5 to 1555 inclusive, that are divisible by 5:

5,10,15,,1555

It forma an AP

a = first term = 5

d = common difference = 10-5=15-10 =5

Formula of nth term :  

Sum of first n terms =  

Substitute n = 311

Hence the sum of all positive integers, from 5 to 1555 inclusive, that are divisible by 5 is 242580
