The numbers are 15, 17, and 19.
225
The numbers are 11, 13 and 15.
15
Must be the 2 odd numbers, 9 & 15 (P = 135, S = 24)
The sum of the first 15 odd numbers is 225.
You can work this out by realizing that the sum of the first x odd numbers is equal to x2.Consider the following examples:The first three odd numbers: 1 + 3 + 5 = 9The first five odd numbers: 1 + 3 + 5 + 7 + 9 = 25The first ten odd numbers: 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 = 100In each case, the number of odds you're adding together is the square root of their sum. This means that the first 1500 consecutive odd numbers have a sum of 15002, which equals 2250000, or two and a quarter million.
The numbers are 15, 17, and 19.
the sum of the first 15 prime numbers is 328 .
225
The nine odd numbers whose sum is 50 are 1, 3, 5, 7, 9, 11, 13, 15, and 1.
The numbers are 11, 13 and 15.
15
Must be the 2 odd numbers, 9 & 15 (P = 135, S = 24)
The sum of six odd numbers is never fifteen since 15 is odd and the sum of six even numbers is always even. However if "make" allows products: 1* 1 * 1 * 1 * 3* 5 = 15 ( I used * to mean multiply.)
The numbers are 13, 15 and 17.
They are: 13+15+17 = 45
