Q3) Sorry if the formatting is off...

Original 7 11 14 15

1st Dif 4 3 1

2nd Dif -1 -2

3rd Diff -1

So it might be a cubic quadratic (third level difference -1) but there aren't enough given numbers to be certain and anyway he hasn't covered quadratic series yet let alone cubic quadratic.

Q4) Not a clue.

Photocopies of the questions were provided so no typos unless the teacher made them.

We're missing something but what?
