The explicit formula is finding the 7th term (a7).
The given explicit formula is finding the value of the 7th term (a7) in the sequence.
The explicit formula given is a7= −12 + (n − 1)(−4). This formula is used to find the nth term of a sequence. In this case, the formula is specifically finding the 7th term of the sequence. The term "a7" represents the 7th term of the sequence. So, the formula is finding the 7th term.
