Home work...You have to do it on your own. Read about matrix/ vector indexing. If you have a amtrix A, you can access (i,j) element by A(i,j). If you have a vector X, you can acess any element using X(i), i = 1...n. Where n is length of vector.
Your problem is very easy and straight forward.

This is basic MATLAB, the key is to understand how MATLAB works. In order to access say the
element of an array X, you call it by X(n). This can be extended to accessing any element (i,j) of a matrix X, as X(i,j).

Now, wrt your problem we need X(161) + X(271), which is the exact syntax as well! It is very intutively written in terms of matrices. Since you have an array/1D matrix you need not worry about the other dimensions.
