Answer
I: 2n+2=24
Work Step by Step
First lets represent our first odd number with n. Then the next consecutive odd number will be n+2 because all consecutive odd number have a difference of 2 between each other. Now we add the two expressions:
n+n+2=2n+2
Finally we equate this with 24 since that is the sum of the two consecutive odd numbers given in the problem:
2n+2=24
In order to find the first odd number, you simply solve for n.
