    Is this really this easy? sequences

    Each of the following sequences has limit 0:
    1/n, 1/n^2, 1/sqrt(n), 1/10^n
    a) For each sequence, state exactly how large n must be to ensure that the term an of the
    sequence (and all later terms as n increases) satisfy abs(an) < 10^-4.

    Do you just do 1/n<10^-4 and solve for n and then do the same for the other 3 or am I making it too easy?
