How do I solve this? Use inductive reasoning to predict the next line in the pattern. 18 + 81 = 99 19 + 91 = 110 A. 101 + 20 = 121 B. 20 + 101 = 121 C. 88 + 33 = 121 D. 20 + 101 = 162 What's inductive reasoning?

I got it wrong. And I don't know why. I had A.

OpenStudy (anonymous):

no it was B

OpenStudy (yanasidlinskiy):

Mind explaining?

OpenStudy (anonymous):

because you can see that the smaller number is in the front and the bigger number is in the back 18 + 81 = 99 19 + 91 = 110

OpenStudy (anonymous):

A is 101 + 20 but B is 20 + 101 which fits with the pattern of the question

OpenStudy (anonymous):

do you understand a little bit more clearly now?

OpenStudy (yanasidlinskiy):

Kind of...Where did those #'s come from though?
