Answer:
-24
Explanation:
Hey there!
First we need to find the ratio
ratio = -6/-3 = 2
r = 2
-3, -6, -12, ? , -48
T1 = a
T2 = ar
T3 = ar²
T4 = ar³
T5 = ar⁴
And so on...
T1 means first term, T2 means second term
We're finding the fourth term which is T4
Remember T1 = a = -3
So, T4 = ar³
= -3 × 2³
= -3× 8
= -24
Therefore, the fourth unknown term is -24
You're welcome y'all
