Sarah counted the number of tiles at each step and made a table. She explained that the number of tiles in each figure was always 3 times the step number minus 2.

Create an equation that fits Sarah's way of seeing the relationship.

PLS HELP DUE IN 10 min!!

n(number of tiles) x 3 - 2

Step-by-step explanation:

times mean multiplication and minus mean subtraction, I hope this helps.

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

answer: 5100 just subtract
