An exponential function repeatedly multiplies an initial amount by the same positive number called the constant ratio. For example, this is commonly used in geometric sequences and the constant ratio is the ratio between all the numbers in the sequence. I will put an example below:
Find the constant ratio of the geometric sequence:
2, 4, 8, 16, 32, 64
Divide each number to the one before it.
4 / 2 = 2
8 / 4 = 2
16 / 8 = 2
32 / 16 = 2
64 / 32 = 2
So, the constant ratio is 2 between all the numbers.
Best of Luck!
