Question
find 3 consecutive odd integers such that five times the 1st increased by the second is equal to four times the 3rd integer

Answer
Hello, Suncerae!

Consecutive odd integers "go up by 2's".

Let x = first odd integer
x + 2 = second odd integer
x + 4 = third odd integer

We are told: "First increased by second equals 4 times third".

This translates to: x + (x + 2) = 4(x + 4)

Then we have: x + x + 2 = 4x + 16 --> -2x = 14 --> x = -7

Answer: -7, -5, -3
