Oh, what a happy little question! To find the sum of the first 500 multiples of 3, we can use the formula for the sum of an arithmetic series: (n/2) * (first term + last term). In this case, the first term is 3 and the last term is 3 * 500. Plugging these values in, we get (500/2) * (3 + 1500) = 250 * 1503 = 375,750.

The first 50 multiples of 6 are the first fifty even multiples of 3.
Well, darling, the sum of the first 500 odd numbers is 500^2, which is 250,000. So, grab a calculator and impress your friends with that little nugget of math knowledge. You're welcome!
just count by 3's upto 500. For Example: 3, 6, 9, 12, 15, 18, 21, 24, etc.....upto 500
