Answer:
Step-by-step explanation:
We want to find the formula for this problem in the explicit form of:
, where
is the nth term,
is the first term, and d is the common difference
Here, we can say that the "first term" is the 15th term, which is 0, so instead of a_1, we have a_15. The nth term is the 40th term, which is -50, so instead of a_n, we have a_40:
d = -2
Now, we need to find the first term:
a_1 = 28
Finally, our equation is:
