Solution for f(n)=f(n-1)(-.25) equation:


Simplifying
f(n) = f(n + -1)(-0.25)

Multiply f * n
fn = f(n + -1)(-0.25)

Reorder the terms:
fn = f(-1 + n)(-0.25)

Reorder the terms for easier multiplication:
fn = -0.25f(-1 + n)
fn = (-1 * -0.25f + n * -0.25f)
fn = (0.25f + -0.25fn)

Solving
fn = 0.25f + -0.25fn

Solving for variable 'f'.

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

Add '-0.25f' to each side of the equation.
-0.25f + fn = 0.25f + -0.25f + -0.25fn

Combine like terms: 0.25f + -0.25f = 0.00
-0.25f + fn = 0.00 + -0.25fn
-0.25f + fn = -0.25fn

Add '0.25fn' to each side of the equation.
-0.25f + fn + 0.25fn = -0.25fn + 0.25fn

Combine like terms: fn + 0.25fn = 1.25fn
-0.25f + 1.25fn = -0.25fn + 0.25fn

Combine like terms: -0.25fn + 0.25fn = 0.00
-0.25f + 1.25fn = 0.00
