GHS - Algebra I Topic 6 Lesson 4 Geometric Sequences

How are geometric sequences related to exponential functions? Select all that apply.

• Geometric sequences are exponential functions.

• Geometric sequences have a domain of the natural numbers 1, 2, 3, ... instead of the real numbers.

• Geometric sequences are linear functions.

• Both geometric sequences and exponential functions have common differences.

• Both geometric sequences and exponential functions have quadratic variables.

What is the explicit form of a geometric sequence?

• $a_n=a_1\cdot r^{\left(n-1\right)}$

• $a_n=r\cdot a_{\left(n-1\right)};\ a_1=$ (a number)

• $y=mx+b$

• $f\left(x\right)=a\cdot b^x$

• $f\left(x\right)=a\left(x-h\right)^2+k$
