# Year 7 maths problem watch

1. Okay, I need help for my kiddy wink who is trying really hard to solve the following question:

A sequence has first term 1 and term to term rule 'x 3-1'. Write down the first four terms of the sequence.

If anyone can describe the steps needed to solve this I would be very grateful. Thank you.
2. Think you've missed something between the x and the 3
3. You substitute the 1 into x - that will be the first term
then you substitute 2 into x that will be the second term
do this with x being 3 and 4 until you get your 4 terms.

I think this is what you are referring to

"term to term rule 'x 3-1'"

This means that to get from one term to the next you first multiply by 3 and then minus 1

So if the first term is 1 then the next term will be:

1 multiplied by 3 = 3
3 minus 1 = 2

So the second term in the sequence is 2.

etc.
5. Thank you all for your very fast responses, they are much appreciated.
