Ex/ 1+2

2+2

3+2

4+2

My question is... I can't figure out what the pattern is in the following set...

1 goes to 4

2 goes to 7

3 goes to 10

and 4 goes to 13......

I initially thought that it was 3x + 2 but it does not work for the third. Can you help?

2 + 5 = 7

3 + 7 = 10

4 + 9 = 13

5 + ? = 16

You might show her with subtraction:

4 - 1 = ?

7 - 2 = ?
