Question

Find the three consecutive natural numbers such that the sum of the first and second is 15 more than the third

Answer 1

We can write the numbers as m-1, m and m+1

Then m-1+m=m+1+15
m=17
So the numbers are 16, 17 and 18

Answer 2

Answer

Let numbers = x, x+1, x+2

x + x + 1 = x + 2 + 15

=> 2x = 17 + x - 1

=> x = 16

Numbers = 16, 17, 18
