Functions 11: Series and Sequences

posted by .

4m + 1, m + 1 and 10 - m are the first three terms of a geometric sequence. Find t4.

  • Functions 11: Series and Sequences -

    since the difference is constant,

    (m+1)-(4m+1) = (10-m)-(m+1)
    m = -9

    so the sequence is

    -35, -8, 19, 46, ...

    But they are not geometric sequence..
