You can never be sure of an answer for any problem like this. Any pattern you see in the numbers might be completely different from what the author of the problem had in mind.

In this example, I'm wondering if the first statement is supposed to say 111=13 instead of just 11=13. Then all the numbers would follow a pattern.

Looking at the separate sequences of the first and second numbers, each time the first number goes up by 1, the second number goes up by 11. Following that pattern, the jump from 114 to 117 is 3; 11 times 3 is 33; so the second number for 117 would be 46+33 = 79.

That method of finding an answer uses the previous numbers in the sequences of inputs and outputs. You can also develop a rule that directly determines the output from the input:

111 --> 11,1 --> 11(1)+2 = 13

112 --> 11,2 --> 11(2)+2 = 24

113 --> 11,3 --> 11(3)+2 = 35

114 --> 11,4 --> 11(4)+2 = 46

And following this pattern we would have

117 --> 11,7 --> 11(7)+2 = 79

But, again, while this looks like a nice solution to the problem, it can only be a guess.
