The nth term of an arithmetic sequence with the first term A and common difference B, can be expressed as:
The explicit rule given is in simplified form, so we need to find the first term and common difference.
We plug 1 for n, in the given rule, and we get:
We know the first term in 37. To find the common difference, we want to find the second term.
The common difference is 26 - 37 = -11.
You are correct.
I hope this helped,
