Atree is 9 centimeters taller each year than it was the year before. if you write down the height each year, what kind of sequence will you have?
arithmetic, geometric or both or none

Arithmetic sequence.

Step-by-step explanation:

Suppose  we start from a tree 9 cm tall.

Each year the height will increase by 9cm:

So year be year the heights will be:

9, 18, 27, 36

This is an Arithmetic Sequence because it has a common difference of 9.

final total: 63

step-by-step explanation:

60 times sales tax

60 times 0.05

3

60 + 3

63
