What is the 4th and 8th element of a= n^(2) ?Question 14Select one:a.32,64b.16,64c.64,16d.8,16

1. Break Down the Problem

We need to find the values of the function $a = n^2$ at $n = 4$ and $n = 8$.

2. Relevant Concepts

The mathematical function given is $a = n^2$. We will substitute $n$ with the required values:

• For the 4th element, substitute $n = 4$.
• For the 8th element, substitute $n = 8$.

3. Analysis and Detail

1. Calculate the 4th element: $a_4 = 4^2 = 16$

2. Calculate the 8th element: $a_8 = 8^2 = 64$

4. Verify and Summarize

• The 4th element $(n=4)$ is $16$.
• The 8th element $(n=8)$ is $64$.

Final Answer

The 4th and 8th elements are $16$ and $64$, respectively. Thus, the correct option is b. 16, 64.
