Answer:

3, 5, 7

Explanation:

You asked for the first two consecutive odd intergers, but then tell of the some of the first three. Are you looking for 2 numbers or 3? Are all the numbers consecutive odd integers. I made the assumption that you are looking for 3 consecutive odd integers.

x = first number

x + 2 = the second number

x + 4 = the third number

x + (x +2) + (x+4) = (x+2) + (x+4) + 3 I put the parentheses in so it would be easer to see the first number, second number and third number. I do not need the parentheses so I will remove them now.

x + x + 2 + x + 4 = x + 2 + x + 4 + 3 Combine line terms

3x + 6 = 2x + 9 Subtract 2x from both sides

x + 6 = 9 Subtract 6 from both sides

x = 3

This first number is 3, the second number is 5 and the third number is 7.
