Determine and state whether the sequence 1, 3, 9, 27, ... displays exponential behavior

1,3,9,27 does indeed display exponential behavior.

Step-by-step explanation:

This is because 1 is multiplied by three and every number coming after it. And exponential behavior means numbers are increasing by 3 which is all the same value. For example, one of the definitions is "Exponential behavior occurs when a function increases or decreases at a rate proportional to its current value."
