Answer: 16, 17 and 18
Step-by-step explanation:
Let the consecutive natural numbers be x, x+1, and x+2. We are informed that the sum of the first and the second is 15 more than the third. This will be:
[x + x + 1] = [x + 2] + 15
2x + 1 = x + 2 + 15
2x + 1 = x + 17
2x – x = 17 – 1
x = 16
The numbers are 16, 17 and 18.
