Question

Find the sum of multiples of 3 from 15 to 50

Answer 1

Answer:

I  think you are asking about the count. If its the count then the count of numbers that are divisible by 3 from 15 to 45 is 11.

15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45.

here is a simple formula,

((first number - last number)/difference)+1

((45–15)/3)+1=(30/3)+1=10+1=11

simple : )
