How use Maple12 to solve a differential equation by using Euler's method? Consider the differential equation $y^{\prime}=y-2$ with initial condition $y\left(0\right)=1$. 
a) Use Euler's method with 4 steps of size 0.2 to estimate $y\left(0.8\right)$ 
I know how to do this by hand; however, I have maple 12 installed and was trying to figure out how to do this with Maple, and then make a graph showing each step of the function.  Any suggestions.  I have tried looking on mapleprimes, but it keeps pointing me to functions for newer versions of maplesoft, which I don't have. 
I posted this question to use as a model, because I have solved this problem by hand and it will help me edited it for other differential equations. 
ps. I hope this is the proper place to ask this question, if not please tell me where would be a better place. 

maybe this would help  ,just change initially condition  and  step size

i am not sure that is is for maple12,but i think commands would be same,just try it and if there is  errors,post here
use also
