the answer is 72.:)
45
72
92 - 18 = 72 72 - 16 = 56 56 - 14 = 42 42 - 12 = 30 30 - 10 = 20 20 is the next number in the sequence.
The next number in the series 3, 618, 72, is -1635. The relevant rule is Un = (-1161n2 + 4713n - 3546)/2 for n = 1, 2, 3, ...

3 * 2 = 6 * 3= 18 *4 =72 *5 = 360
360 each number is multipled by (2 + the preceding term number) 3 x 2 = 6 6 x 3 = 18 18 x 4 = 72 72 x 5 = 360
78,72,66,60,54 what is the next number
