a1 = −8
a6 = an +5
What term is this formula solving for?
This formula is solving for the 6th term (a6) in the sequence.
This formula is solving for the term with the index "n".
The formula you provided is a recursive formula for the sequence (a1, a2, a3, ...) where a1 is -8 and a6 is given in terms of a previous term, an, as an + 5.
To determine what term the formula is solving for, we can analyze the pattern in the formula. We see that a6 (the 6th term) is being expressed in terms of an (the nth term) for some value of n. Therefore, the formula is solving for the nth term of the sequence.
