    Answer:

    A sequence can be used to illustrate the difference in heights of each jump and develop a pattern from them. In this case, we have 27, 18, 12,… Assuming the pattern continues, we have the previous height divided by 3 and then subtracted from itself:n

    A Geometric sequence can be used:
    To Model this sequence you need to use this formula
    A (subscript n) = Ar(n-1)
    a = value of the first term
    n = the # of the term you want to find (For example, if you want to find the term number 3, it is 12)
    r = the common ratio, this is obtained by dividing the second term in the sequence by the first.
    So the value of r is = 2/3 because 27 times 2/3 = 18 which is the second term
    n = 4 since you want to find the 4th term in the sequence
    Plug it in and results are
    4th term= 27(2/3)^(4-1)= 8
    The answer is 8
