One term of a geometric sequence is a4=135. The common ratio is r=3. Write an explicit rule for the nth term.

Step-by-step explanation:

To find the nth term of a geometric sequence, you have the general formula:

where a1 is the first term and r is the common ratio. In order to find the 4th term, we can substitute what we have(n is 4 because we are looking for the fourth term):

135 =

135 =

135 =

Now, we can substitute the first term back in:

chase is right because he already been to the swings and he know how far it will be to get there

step-by-step explanation:

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
