b n =b 1 ⋅q n−1
Solution
It seems like you've provided a formula for a geometric sequence but didn't ask a specific question. The formula you've given is for the nth term of a geometric sequence, where:
- b_n is the nth term
- b_1 is the first term
- q is the common ratio
- n is the term number
So, if you want to find the nth term of a geometric sequence, you can use this formula by substitifying the values of b_1, q, and n into the formula.
If you have a specific question or need further explanation, feel free to ask!
