Answer:

Hey there!

We have an=a1(r^n-1), which is the formula for a geometric sequence.

The common ratio is 3, and 2 is the 1st term.

Thus, we have a1=2(3)^(n-1)

Hope this helps :)

valentina_108 [34]

Answer:

22 groups of ten

Step-by-step explanation:

121 plus 116 = 237

237 - 9 = 228

lets split 228 into parts

200

20

8

there are 20 groups of ten in 200

2 groups of ten in 20

and 8 has 0 it is a remainder

20 groups plus 2 groups = 22

22 groups of ten

this probobly isn't the easiest way but I don't know how but this is my thought process.
