Solution for f(n)=f(n-1)+7 equation:


Simplifying
f(n) = f(n + -1) + 7

Multiply f * n
fn = f(n + -1) + 7

Reorder the terms:
fn = f(-1 + n) + 7
fn = (-1 * f + n * f) + 7
fn = (-1f + fn) + 7

Reorder the terms:
fn = 7 + -1f + fn

Add '-1fn' to each side of the equation.
fn + -1fn = 7 + -1f + fn + -1fn

Combine like terms: fn + -1fn = 0
0 = 7 + -1f + fn + -1fn

Combine like terms: fn + -1fn = 0
0 = 7 + -1f + 0
0 = 7 + -1f

Solving
0 = 7 + -1f

Solving for variable 'f'.

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

Add 'f' to each side of the equation.
0 + f = 7 + -1f + f
Remove the zero:
f = 7 + -1f + f
