I need help 2.Look at the sequence of values for the first coordinate in the vectors youcomputed for # 1. These are values in a famous mathematical sequence youmay or may not recognize. What numbers are we generating? 3. The sequence of numbers we’re generating are traditionally constructedlike this: Start with the first 2 numbers. To get the next number, take the 2most recent numbers and add them together to get the next one.Explain why our matrix vector multiplication is generating the same numbersas the traditional procedure.

First recall the following notation and results discussed in class: col,(A) denotes the jth column of an n x m matrix A with entries from F, that is, col,(A) E F, the set of column vectors with n rows. For any p x n matrix B and any n x m matrix A, the definition of matrix multiplication gives that col, (BA) — В соl,(А), j — 1, 2, ..., т. In the special case that A is a column vector (ie m = 1) with entries 21,..., En , then the above gives that BA =x,col1 (B) + x2col2(B)+.+¤ncol,(B). Given a basis By : V1,..., Vn for a vector space Vover F, for any v E V , the "matrix of v" given in Definition 3.62 of the textbook is also called the "coordinate vector of v with respect to the basis By", that is [v)Bv = M(v) E F,1. Given two finite dimensional vector spaces V and W over F and any linear map T E L(V,W), let By : v1,..., Vn be a basis for V and Bw : w1,..., wm be a basis for W. Then from Definition 3.32 of the textbook for the matrix of T we know that: col,(M(T)) = [Tv;]Bw= M(Tv;). In…
