5-57.

Write an explicit equation for the following sequences. Homework Help ✎

1. $500$, $2000$, $3500$$\dots$

1. $30$, $150$, $750$, $3750$, $\dots$

Decide if each sequence is arithmetic or geometric.
Arithmetic sequences have a common difference.
Geometric sequences have a common multiplier.

Refer to the Math Notes box in Lesson 4.1.3 for the equations for arithmetic and geometric sequences.
