Solution for A(n)=0.2+(n-1)(1) equation: 


Simplifying
A(n) = 0.2 + (n + -1)(1)

Multiply A * n
nA = 0.2 + (n + -1)(1)

Reorder the terms:
nA = 0.2 + (-1 + n)(1)

Reorder the terms for easier multiplication:
nA = 0.2 + 1(-1 + n)
nA = 0.2 + (-1 * 1 + n * 1)
nA = 0.2 + (-1 + 1n)

Combine like terms: 0.2 + -1 = -0.8
nA = -0.8 + 1n

Solving
nA = -0.8 + 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 = -0.8 + 1n + -1n

Combine like terms: 1n + -1n = 0
-1n + nA = -0.8 + 0
-1n + nA = -0.8

Reorder the terms:
0.8 + -1n + nA = -0.8 + 0.8

Combine like terms: -0.8 + 0.8 = 0.0
0.8 + -1n + nA = 0.0
