Answer:
f(n) = -8 -3(n -1)
Step-by-step explanation:
The given recursive formula tells you that the difference between two sequential terms is -3, and that the first term is -8. This is a formula for an arithmetic sequence, so we can use the explicit formula ...
f(n) = a1 +d(n -1)
for a1 = -8 and d = -3.
f(n) = -8 -3(n -1)
23.75 is the square root of 564
What function you haven't even provided the formula
