Consider the quadratic sequence {T} = {-8, that is, this should be viewed as a sequence T = a. Find the nth term for this sequence. T = b. What is the value of T4 ? T = - - 10, 10, ...} an + bn + c for some constants a,b, and c. c. Suppose the difference between two consecutive terms in this sequence is 18. Find the values of these terms, i.e. list the two terms in order.
