    I would take the midpoints at (1,3,5,7,9). Just because 10 isn't a midpoint. You don't know the value at 11.

    It shouldn't really matter ... but midpoints are always the best.

    For understanding plot these points and see what happens
    if pick left points, middle points, or right points
