f(n+1)=F(n)+3

Solution for f(n+1)=F(n)+3 equation:

Simplifying
f(n + 1) = F(n) + 3

Reorder the terms:
f(1 + n) = F(n) + 3
(1 * f + n * f) = F(n) + 3
(1f + fn) = F(n) + 3

Multiply F * n
1f + fn = nF + 3

Reorder the terms:
1f + fn = 3 + nF

Solving
1f + fn = 3 + nF

Solving for variable 'f'.

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

Reorder the terms:
-3 + 1f + fn + -1nF = 3 + nF + -3 + -1nF

Reorder the terms:
-3 + 1f + fn + -1nF = 3 + -3 + nF + -1nF

Combine like terms: 3 + -3 = 0
-3 + 1f + fn + -1nF = 0 + nF + -1nF
-3 + 1f + fn + -1nF = nF + -1nF

Combine like terms: nF + -1nF = 0
-3 + 1f + fn + -1nF = 0
