A function f(x) has these properties:
F(1)= 1
F(x+1)= f(x) + 3x(x+1)
Determine f(3)
the answer is 27
I thnk that they are all meant to be capital Fs
A function F(x) has these properties:
F(1)= 1
F(x+1)= F(x) + 3x(x+1)
Determine F(3)
the answer is 27
--------------------
F(1)=1
F(2) = F(1+1)=F(1)+3*1*(1+1) = 1+6=7
F(3) = F(2+1)=F(2)+3*2*3 = 7+18 = 25
the answer is 25 not 27.
It would be interesting for someone to find the equation for this sequence. (Without it being recursive)
