If the sequence is determined by 100 - 70 = 30, then the next number is 10.
The next number in the sequence 100,96,104,88,120,56 is 184.The pattern is minus 4, plus 8, minus 16, plus 32, minus 64, plus 128

500
The next number is 48.
121
Do you mean the next number or the sequence equation. And there isn't a solid patter, there's to much ambiguity to determine a logical next number.
A sequence never ends. The next number in this one is 7 .
Each is half of the previous number, so 6.25 will be next.

144
The differences betweent the consequent members are: 48, 24, 12, 6 - the next is equal to the previous divided by two. So the next difference will be 6:2 = 3 and the next member of the sequence will be 10 - 3 = 7
