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
