Which word best describes this formula for the sequence an? an = 7(-9)^(n + 3) + 7 Choices: (A)explicit (B)recursive

Identify Formula: Look at the formula: a_n = 7(-9)^(n + 3) + 7. 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 the index n directly.Confirm Explicit Formula: So, since the formula gives the nth term directly without needing previous terms, it's an explicit formula.Correct Description: Choice (A) explicit is the correct description for the formula a_n = 7(-9)^(n + 3) + 7.

Identify Formula: Look at the formula: $a_n = 7(-9)^{(n + 3)} + 7$ . 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 the index $n$ directly.
Confirm Explicit Formula: So, since the formula gives the $n$ th term directly without needing previous terms, it's an explicit formula.
Correct Description: Choice (A) explicit is the correct description for the formula $a_n = 7(-9)^{(n + 3)} + 7$ .
