    \[u _{n}=u _{n-1}+d\]

    I saw that the equation would be y=-2x +4 but need a general solution in terms of recurrence

    un=un−1+d if this is the general formula that the answer should be u0 + n times d

    y=-2x +4 this is the same as I wrote first just written as a function

    Use iteration (by hand or with your calculator) to explore the first few terms of each sequence. ii. On the basis of (i), conjecture a formula for a solution u(n) of the general affine system with r=1: (I) u0=c (R) un=un-1+d for n > 0
