-3,-12,48,-192 what is the 9th term of the sequence
To find the 9th term of the sequence, we need to first find the pattern or the rule for generating the sequence.
Let's take a look at the given sequence -3, -12, 48, -192. Notice that each term is obtained by multiplying the previous term by -4.
To make it more clear, let's write out the first few terms of the sequence:
-3 (1st term)
-3 * (-4) = 12 (2nd term)
12 * (-4) = -48 (3rd term)
-48 * (-4) = 192 (4th term)
From the pattern, we can see that to get the next term, we multiply the previous term by -4.
Now let's apply this pattern to find the 9th term.
Start with the first term: -3
Multiply by -4 eight times, since we want to find the 9th term:
-3 * (-4)^8
Now, let's calculate this expression:
=(-3) * (256)
=-768
Therefore, the 9th term of the sequence is -768.
It would be a geometric sequence if the first term is +3
then
a = 3
r = -4
term(9) = ar^8 = 3(-4)^8 = ...
The way you typed it, it does not form a geometric sequence.
