    Your question seems unfinished but I managed to look for the correct question. Below is the solution:

    U[0] = (1/2) kx[0]^2

    U[1] = (1/2) k (2x[0]) ^2 = 4. (1/2) kx[0]^2 = 4U[0]

    U[2] = (1/2) k (x[0]/2) ^2 = (1/4). (1/2) kx[0]^2 = U[0]/4

    2U[0] = 2 (1/2) kx[0]^2 = (1/2) k{sqrt (2) x[0]}^2

    Compression sqrt (2) x[0]

    The last one is similar.
