n'+ 4n 4n-2<0.

To solve the inequality \( n' + 4n - 4n - 2 < 0 \), we first simplify it.

1. Combine like terms: The terms involving \( n \) on the left side cancel each other out. \[ n' - 2 < 0 \]

2. Isolate \( n' \): \[ n' < 2 \]

This means that the derivative \( n' \) is less than 2.

If \( n' \) represents the derivative of a function \( n(t) \) with respect to time \( t \) or another variable, it indicates that the rate of change of \( n \) is less than 2.
