Arecursive rule for a geometric sequence is a1=49; an=3an−1. what is the explicit rule for this sequence?

Step-by-step explanation:

A recursive rule for a geometric sequence is a1=49;an=3an−1

First term a1= 49

To get second term, multiply the first term by 3

So common ratio r = 3

Explicit rule for geometric sequence is

a1= 49  and r= 3

So explicit rule is

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

y > 1/3x

y < = -x + 4

hope this : )
