find the fifth term of geometric sequence
a=-6 r=2
This website explains how to do it:

However, you must designate which term in the sequence is what you call "a". Is it the f1rst term, a1? If so,
a2 = r* a1 = -12.. etc.
3 1
_______ - _______
x-3 x
To find the fifth term of a geometric sequence, you can use the formula:
an = a1 * r^(n-1)
In this case, a1 is the first term of the sequence, and r is the common ratio.
Given that a = -6 and r = 2, we can substitute these values into the formula to find the fifth term:
a5 = (-6) * 2^(5-1)
= (-6) * 2^4
= (-6) * 16
= -96
Therefore, the fifth term of the geometric sequence is -96.
