Question

4. Using the given formula below, identify the common ratio:

Answer 1

Answer:

The Common ratio should be 2.5

Step-by-step explanation:

as the formula goes, the first number in a sequence is multiplied by the common ratio, the amount of number space in between two numbers in a sequence, in this case 2.5 in order to get the next number. Hope this helps!

Answer 2

Answer:

2.5

Step-by-step explanation:

Recall that the formula for a geometric sequence is $a_n=a_1(r)^{n-1}$ where $a_1$ is the first term and $r$ is the common ratio.

Thus, the common ratio is $r=2.5$ since each consecutive term is being multiplied by 2.5 when $n$ is an integer. This tells us that the growth rate of the exponential function is 150% since 100%+150%=250%
