Answer:
Step-by-step explanation:
The explicit formula for an arithmetic sequence is
where n is the position of the number in the sequence, a1 is the first number in the sequence, and d is the common difference between the numbers.
If we are looking for the 91st term, our n = 91;
our a1 is 28, and
the common difference is -20. Putting all that together gives us the explicit formula for this sequence:
and
and
so
First, you would need to create an equation for this problem. Let x represent the unknown percentage.
= 
Next, you would cross multiply.
25x = 1,700
Now, all you would have to do is isolate the x. To do this, you would divide both sides by 25.
x = 68%
17 is 68% of 25.
