Question

Find three consecutive odd integers such that the sum of the largest and twice the smallest is 25.
If x represents the smallest integer, then which equation could be used to solve the problem?

Answer 1

selecting three consecutive odd integers would make sense if u select like this 2x+1,2x+3 and 2x+5
bcoz if u select x then how can u justify that it is odd.

Answer 2

Let x = first odd integer
x+2 = 2nd odd integer
x+4 = third odd integer
x+4+2x=25

Answer 3

And then combine terms... :-)

3x + 4 = 25
