N, N+1, (N+1) + 4, (N+1) + 4 + 1, Repeat
Next numbers are 19, 23, 24
add 6, subtract 2
It is (13+14+16+17+17+18)/6.
13 - 14 - 18 - 23 - 32 = -74
rule: add 18 to each number, starting with 18.
13/18 is smaller
mean average = sum of dataset / number of items in dataset = (14 + 18 + 13 + 15) / 4 = 60/4 = 15

18. The pattern is add 5, then subtract 1.
14. The rule is t(n) = (-7n3 + 57n2 - 110n + 84)/6 for n = 1 , 2, 3, ...
