Question

what is the sum of the first hundred multiples of 5​

Answer 1

Step-by-step explanation:

This would be a series: 5 + 10 + 15 + 20 +...+ 500

there are n terms → n = 100

the nth term is 500

to find the sum of the series, you take the sum of the first and last terms and multiply it by (n/2)

(5 + 500) * (100 / 2)

505 * 50 = 25250
