    Instantaneous rate of change using secant method

    I have a question regarding using the secant method.

    say for example I have to find the instantaneous rate of t=3 and we will give the points as following: (3, 6.9) my question is should the next point be ahead at say 2.5 or at 3.5?

    thanks

    Both points of the secant line should approach the point of interest, namely, t = 3. Hence, in this case, what I would probably do is bring the 6.9 point closer, since the other point is already there.
