The sequence is Un = (125n6 - 3131n5 + 31065n4 - 154445n3 + 399010n2 - 496304n + 228480)/240 for n = 1, 2, 3, ...
The next number in the sequence would be 25.
92 - 18 = 72 72 - 16 = 56 56 - 14 = 42 42 - 12 = 30 30 - 10 = 20 20 is the next number in the sequence.

It's, 7n+6
The next number in the sequence would be 25.
16
next in the sequence: 10,20,30,20
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 sequence will be 56.
20
Think it's 30...then 20
10
25 is the next number that appears in that sequence.
44 this is based on a sequence of doubling the initial number then adding 2 to that result.
