First remember that sum means to add. now think about the equation. we need to find 3 numbers that equal 159 when added together. And they are all consecutive odd numbers. so let's call the first number X. the second number would be X+2 since we have to jump over 1 even number. The third number would be X+4 since we have to jump over 2 even numbers. so now an equation to represent this would be X+(X+2)+(X+4)=159. Add like terms, and remember order of operations. if you need help getting the answers leave me a comment.

Answer:
the number is 105
Step-by-step explanation:
5(x+3) = 3(2x - 1)
5x + 15 = 6x - 3
15 = 1x - 3
(15 + 3)
x = 18
