    Problem with series!

    Hello,

    given are the 3 first terms of a series:

    p(3q+1) ; p (2q + 2) ; p (2q-1)

    Use algebra to show that a possible value for q is 5.

    Please help!

    Thx!

    What sort of series? Arithmetic? Geometric?

    Assuming a geometric sequence will give the correct answer for q:

    Apply the condition \frac{2q+2}{3q+1} = \frac{2q-1}{2q+2} and solve for q.
