Suppose f(x) − f(x+1) = 3x^2 and f(3) = 48, determine the value of f(5) show all steps so i can understand how you got to the answer! help please !!

Step-by-step explanation:

f(3) = 48

f(3)-f(4) = 3*3^2

f(4) = 21

f(4)-f(5) = 3*4^2

f(5) = -27

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
