<h2>Answer: C)-16</h2>

Step-by-step explanation:

We have a sequence with the following rule:

t_{(n)}=-2(2)^{n-1}

This gives us the n term of the sequence. Now, if we want to find the fourth term, we have to substitute n by 4:

t_{(4)}=-2(2)^{4-1}

t_{(4)}=-2(2)^{3}

t_{(4)}=-2(8)

Finally:

t_{(4)}=-16 This is the fourth term of the sequence

Andre45 [30]

Answer:

a) Let Kim's age be k, then Kim's sister's age is k/2

k+\frac{k}{2}=24

b) k+\frac{k}{2}=24

1\frac{1}{2}k=24

k=16

\frac{k}{2}=8

Kim's age is 16 while her sister's age is 8.
