SOLUTION: Three consecutive odd counting numbers have the property that the sum of the largest and twice the smallest is 112. What is the middle number?
Hi,
Note: consecutive odd number differ by 2.
Let x, (x+2) and (x+4) represent the numbers
(x+4) + 2x = 112
3x = 108
x = 36
Middle number is 38
checking our answer
40 + 72 = 112
