Question

Two discrete-time signals x[n] and h[n] are both non-zero only for n = 0, 1, 2, and are zero otherwise. It is given that x[0]=5, x[1]=10, x[2]=15, and h[0]=2.

Let y[n] be linear convolution of x[n] and h[n]. Given that y[1] = 25 and y[2] = 50, the value of the expression (2y[3]+y[4])  is
