Pattern: Start with 0, add 2, then add 4, then add 6, then add 8,...
The last term should have 16 added to it, so the next term will be 72.
25 is the next number that appears in that sequence.
16
22
The next number in the sequence will be 56.
The next number in the sequence is 20. You are alternately multiplying the previous number by two and then subtracting two.
25 is the next number that appears in that sequence.
20
20
3, -6, 12, 4, 20, ?
The pattern appears to be: subtract 6, add 17, subtract 14, add 9, subtract 7. Following this pattern, the next number should be obtained by adding 3 to the last number in the sequence, which is 6. Therefore, the next number in the sequence is 9.
56
10 The sequence is given by xn = 60/n
next in the sequence: 10,20,30,20
16
Those are the factors of the number 60, in descending order. The next factor is 10.
22
The next number in the sequence will be 56.
