Ageometric sequence is defined by the explicit formula an = 5(-4)n-1. what is the recursive formula for the nth term of this sequence?

a. an = -5an-1
b. an+1 = 4an
c. an+1 = 5an
d. an = -4an-1

The number of members f(x) in a local swimming club increased by 30% every year over a period of x years. the function below shows the relationship between f(x) and x: f(x) = 10(1.3)xwhich of the following graphs best represents the function? graph of f of x equals 1.3 multiplied by 10 to the power of x graph of exponential function going up from left to right in quadrant 1 through the point 0, 0 and continuing towards infinity graph of f of x equals 10 multiplied by 1.3 to the power of x graph of f of x equals 1.3 to the power of x
