Step-by-step explanation:

Ryan bought a new computer for $2,100.

Price of computer = 2100 $

The value of the computer decreases by 50% each year.

Let p(n) be the price of computer after n years.

$\texttt{Price of computer after 1 year =}2100-\frac{50}{100}\times 2100=0.50^1\times 2100\$\\\\\texttt{Price of computer after 2 years =}0.50^2\times 2100\$\\\\\texttt{Price of computer after 3 years =}0.50^3\times 2100\$\\\\\texttt{Price of computer after n years =}0.50^n\times 2100\$$
