Sum of all integers between 100 and 500 which are divisible by 17
Asked by seeni2005 | 17th Aug, 2020, 12:42: AM
The first and last numbers between 100 and 500 which are divisible by 17 are 102 and 493.
The numbers divisible by 17 forms an AP with common difference d=17, first term a = 102 and last term an = 493
an = a + (n-1)d
493 = 102 + (n-1)17
(n-1)17 = 391
n-1 = 23
n = 24
Now, the formula for sum of n terms of an AP can be used to find the required sum
