What is the formula for the nth term of the sequence 54 18 6?

Notice that this is a geometric sequence because here we have equal common ratio.

So, common ratio :

=

=

The formula for general term of a geometric sequence is,

Where, first term: a_{1} =54.

Next step is to plug in the value of a1 and r in the above formula to get the formula of the given sequence. So,

Hope that helps you!

step-by-step explanation: 4 cause 2+2=4

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
