Answer:
Tn = 4(-6)^n-1
Step-by-step explanation:
Write an explicit formula for an, the nth term of the sequence 4, -24, 144, ....
The sequence is a geometric sequence
Tn = ar^n-1
a is the first term
a = 4
r = -24/4 =144/-24
r = -6
Substitute
Tn = 4(-6)^n-1
(−2)³ = (-2)(-2)(-2)
Note that:
two negative numbers multiplied together results in a positive
one negative and one positive number multiplied results in a negative
Multiply:
(-2)(-2) = 4
4(-2) = -8
-8 is your answer
