F(n)=f(n-1)+2

Solution for F(n)=f(n-1)+2 equation:

Simplifying
F(n) = f(n + -1) + 2

Multiply F * n
nF = f(n + -1) + 2

Reorder the terms:
nF = f(-1 + n) + 2
nF = (-1 * f + n * f) + 2
nF = (-1f + fn) + 2

Reorder the terms:
nF = 2 + -1f + fn

Solving
nF = 2 + -1f + fn

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-1fn' to each side of the equation.
-1fn + nF = 2 + -1f + fn + -1fn

Combine like terms: fn + -1fn = 0
-1fn + nF = 2 + -1f + 0
-1fn + nF = 2 + -1f

Reorder the terms:
-2 + f + -1fn + nF = 2 + -1f + -2 + f

Reorder the terms:
-2 + f + -1fn + nF = 2 + -2 + -1f + f

Combine like terms: 2 + -2 = 0
-2 + f + -1fn + nF = 0 + -1f + f
-2 + f + -1fn + nF = -1f + f

Combine like terms: -1f + f = 0
-2 + f + -1fn + nF = 0
