Step-by-step explanation:
-4= Contraction
2.5=Expansion
2/3= Contraction
-3/4= Contraction
Best way to solve this, if the scale factor is less than one, is a contraction. If it is greater than one, than it is an expansion.
Hello from MrBillDoesMath!
Answer:
b(n) = 12 * 2^(n-1) where n >=1
Discussion:
12* 2 = 24 (second term in sequence)
24 * 2 = 48 (third term in sequence)
48 *2 = 96 (fourth term in the sequence)
So b(n) = 12 * 2^(n-1) where n >=1
b(1) = 12 * 2^ 0 = 12 * 1 = 12
b(2) = 12 * 2^(2-1) =12 * 2 - 24,
Thank you,
MrB
