Find the first four terms of the sequence given the rule:
an = 4(5)n-1

4, 20, 100, 500

Step-by-step explanation:

Assuming that the sequence starts at 1:

Plug in 1, 2, 3, and 4 to the a(n) function to get:

4, 20, 100, 500

step-by-step explanation:

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
