A(n)=6+(n-1)2

Solution for A(n)=6+(n-1)2 equation:

Simplifying
A(n) = 6 + (n + -1) * 2

Multiply A * n
nA = 6 + (n + -1) * 2

Reorder the terms:
nA = 6 + (-1 + n) * 2

Reorder the terms for easier multiplication:
nA = 6 + 2(-1 + n)
nA = 6 + (-1 * 2 + n * 2)
nA = 6 + (-2 + 2n)

Combine like terms: 6 + -2 = 4
nA = 4 + 2n

Solving
nA = 4 + 2n

Solving for variable 'n'.

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

Add '-2n' to each side of the equation.
-2n + nA = 4 + 2n + -2n

Combine like terms: 2n + -2n = 0
-2n + nA = 4 + 0
-2n + nA = 4

Reorder the terms:
-4 + -2n + nA = 4 + -4

Combine like terms: 4 + -4 = 0
-4 + -2n + nA = 0
