FOR THE FOLLOWING SEQUENCES, WORK OUT THE JUMPS
BETWEEN THE NUMBERS TO SPOT THE PATTERN:
Sequence What is it? What comes next?
2, 5, 8, 11 14, 17 add the same number on each time:
in this case +3
54, 162 2, 6, 18 multiply by the same number each time: in this case x3
+1, +2, +3 etc 1, 2, 4, 7, 11,
16
3, 6, 18, 72,
360
1, 2, 4, 8, 16,
3, 6, 12 x2, x3, x4 etc
Doubling the previous number also doubling
1, 4, 3, 6, 5, 8 add three, take away one, repeat
3, 7, 15, 31
1, 2, 2, 4, 3, 6,
4, 8, 5, 10
1, 2, 2, 4, 3, 6, 4, 8, 5, 10
(x2 +1) two sequences in one: top and tail each number and see if there are 2 sequences

7, 10, 9, 12
63, 127
6, 12 first sequence is 1, 2, 3, 4, 5 so the next number is 6 second sequence is 2, 4, 6,
8, 10 so the next number is
