Question

If F(n) = F(n-1) + (n-1)

F(5) = 11

What is F(1)?

Answer 1

Math help needed.

Answer 2

Use the recursion relation that they gave you, backwards.
F(n-1) = F(n)-(n-1)
Let n = 5 for starters
F(4) = F(5) -4 = 7
Now let n = 4
F(3) = F(4) -3 = 4
Coininuing in this manner,
F(2) = F(3) -2 = 2
F(1) = F(2) -1 = 1
