If 3x + 1 represents an odd integer, which of the following represents the next larger odd integer?

(A) 3(x + 1)

(B) 3(x + 2)

(C) 3(x + 3)

(D) 3x + 2

(E) 3(x + 2) + 1

Some odd numbers: 1, 3, 5, 7, 9, 11, 13, 15,...

Notice that each successive odd number is

2 greater than the previous odd numberSo, the next odd number (after 3x + 1) will be

3x + 1 + 2Since 3x + 1

+ 2 is not among the answer choices, we'll have to rewrite it.

First off, 3x + 1

+ 2 =

3x + 3Check the answer choices again....still not there.

We can take 3x + 3 and factor out the 3 to get:

3(x + 1)Check the answer choices again....BINGO!

Answer: A

Cheers,

Brent
