    How to calculate the geometric sequence?

    A geometric sequence is defined as a sequence in which the result of the division of consecutive terms is always the same, called common ratio r.
    The nth term of a geometric sequence is given by:
    aₙ = a₁rⁿ⁻¹
    where;
    a₁ is the first term
    r is the common ratio
    In this question, on the first week there are 6 people, and since each new people involve three more, the common ratio is 3, hence the parameters for the geometric sequence are:
    a₁ = 6
    r = 3
    Hence the number of people after n weeks is:
    aₙ = 6(3)ⁿ⁻¹
    Thus, the number of volunteers recruited for the first 5 weeks is;
    a₅ = 6(3)⁵⁻¹
    a₅ = 6 * 3⁴
    a₅ = 486
