Sorry if I sound a bit dim but I am in a bit of a panic as I have a son worried about his homework which is due in tomorrow. He has a sheet with two rows and five columns as follows:
Position 1 2 3 4
Term 9 13 17 21
The first question is:
a. What is the term to term rule? (how do you get from 9 to 13, 13 to 17?)
I have worked this out as the term rule is term + 4.
The next bit has thrown me:
b. What is the position to term rule? (how do you get from 1 to 9, 2 to 13?)
The position to term rule is (position number x ......)
Completely lost, can anybody help and advise on how I can explain this to my son?
Many thanks in advance.
