First we discovered all the things that it could be. Some people thought it looked like a flower and others thought it looked like a minecraft flower. At first I thought it looked like a stamp that looked like a plus.
Then we organised our thinking into a chart. We found out that each time the pattern grew it added five. It added one to the top and one on the four sides.
Number in Sequence
Number of Cubes
We drew the next two in the sequence so we could check if it was right. We thought that we would find the tenth in the sequence. We did this by adding five.
From there we did trial and improvemnet to find a formula.
The formula is y = (y-1)5 +1
(y is the sequence)
BEDMAS is to help us with order of oprations it help us make the formula.
