A(n)=4+(n-1)(1)

Solution for A(n)=4+(n-1)(1) equation:

Simplifying
A(n) = 4 + (n + -1)(1)

Multiply A * n
nA = 4 + (n + -1)(1)

Reorder the terms:
nA = 4 + (-1 + n)(1)

Reorder the terms for easier multiplication:
nA = 4 + 1(-1 + n)
nA = 4 + (-1 * 1 + n * 1)
nA = 4 + (-1 + 1n)

Combine like terms: 4 + -1 = 3
nA = 3 + 1n

Solving
nA = 3 + 1n

Solving for variable 'n'.

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

Add '-1n' to each side of the equation.
-1n + nA = 3 + 1n + -1n

Combine like terms: 1n + -1n = 0
-1n + nA = 3 + 0
-1n + nA = 3

Reorder the terms:
-3 + -1n + nA = 3 + -3

Combine like terms: 3 + -3 = 0
-3 + -1n + nA = 0
