3 times the first of three consecutive odd integers is 3 more than twice the third? what is the third integer

15

Step-by-step explanation:

The difference between consecutive integers is 1.

The difference between consecutive odd integers is 2.

Let the smallest odd integer be x.

Then the next greater one is x + 2. The greatest one is x + 4.

"3 times the first" is 3x

"twice the third" is 2 (x + 4)

"3 times the first of three consecutive odd integers is 3 more than twice the third"

3x = 2 (x + 4) + 3

3x = 2x + 8 + 3

x = 11

The smallest integer is 11.

x + 4 = 11 + 4 = 15

The greatest one is 15.
