    7) Show that the infinite sum of 256 + 192 + 144 + .... is 1024 (done this)
    Find the least number of terms 256 + 192 + 144 + .... is within 1 x 10^-6 of 1024

    What does the last part of the question even mean? I feel incredibly stupid, but I might not have been in the lesson something like this was taught and my teacher probably neglected to tell to go over this

    If a number x is within .... of .... (eg within 5 of 23...) then  18 \leq x \leq 28 for example. And 1x10^-6 is  \frac{1}{10^{6}} = 0.000001.

    Admittedly I'm unsure of whether the 'within' implies strict or not but chances are it won't matter for your question.
