Which word best describes this formula for the sequence an? an = -(-1)^(n + 3) + 4 Choices: (A)explicit (B)recursive

Examine the Formula: Look at the formula: a_n = -(-1)^(n + 3) + 4. Does it use previous terms of the sequence to find the nth term?Determine Use of Previous Terms: No, it doesn't use previous terms. It calculates the nth term using only the index n.Identify Explicit Formula: So, since the formula gives a direct way to find any term in the sequence using the position n, it's called an explicit formula.

Q. Which word best describes this formula for the sequence

a_n

\newline

a_n = -(-1)^{(n + 3)} + 4

\newline

Choices:

\newline

(A) explicit

\newline

(B) recursive

\newline

Examine the Formula: Look at the formula: $a_n = -(-1)^{(n + 3)} + 4$ . Does it use previous terms of the sequence to find the $n$ th term?
Determine Use of Previous Terms: No, it doesn't use previous terms. It calculates the $n$ th term using only the index $n$ .
Identify Explicit Formula: So, since the formula gives a direct way to find any term in the sequence using the position $n$ , it's called an explicit formula.
