F(x)=2x^2+5x-8 is an example of a non-linear equation. Anything with x is linear, anything with x raised to a power (any power except 0 and 1) is non-linear.
The pattern is +4.
The rate of change is 4.
Equation: y=4x+6
Thanks for requesting me to answer! I am not sure what the difference between pattern and rate of change is but I hope this helps.
