    This is the question if Ur+1=MUr+c. Find the value of m and c where Uo=-1 ,U1=7, and U2=9

    Taking Ur to be U subscript r indicating a real number:

    You need to substitute the values for Uo, U1 and U2 into the expression Ur+1=MUr+c to get 3 simultaneous equations.

    You can then find the values for m and c.
