Find the equation of the exponential function represented by the table below:

X
0
1
2
3
Y
1
0.5
0.25
0.125
Y =

an = 0.5^n−1

Step-by-step explanation:

Use the formula :

a_n = a_1r^n−1

To identify the geometric sequence.

an = 0.5^n−1

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
