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

Look at the formula: Look at the formula: a_n = -3n^3. Does it use previous terms of the sequence to find the nth term?No, it doesn't: No, it doesn't. The formula only uses the index n to find the nth term directly.Formula not recursive: So, the formula is not recursive because it doesn't require the previous term(s) to calculate the current term.Formula is explicit: Therefore, the formula is explicit since it provides a direct way to find any term in the sequence by plugging in the value of n.

Q. Which word best describes this formula for the sequence

a_n

\newline

\newline

a_n = -3n^3

\newline

\newline

Choices:

\newline

(A)explicit

\newline

(B)recursive

Look at the formula: Look at the formula: $a_n = -3n^3$ . Does it use previous terms of the sequence to find the $n$ th term?
No, it doesn't: No, it doesn't. The formula only uses the index $n$ to find the $n$ th term directly.
Formula not recursive: So, the formula is not recursive because it doesn't require the previous term(s) to calculate the current term.
Formula is explicit: Therefore, the formula is explicit since it provides a direct way to find any term in the sequence by plugging in the value of $n$ .
