Question

Luiza's savings account had

Answer 1

Answer: g is a geometric sequence.

Step-by-step explanation:

Each year since then, her account accumulated interest amounting to

15% of the balance in the previous year.

15% = 15/100 = 0.15

Since the balance is increasing each year, then the constant factor by which it is increasing is 1 + 0.15 = 1.15.

This factor of 1.15 is a common ratio. This means that the sequence is a geometric sequence since it is increasing by a common ratio.
