the rule is times by 4 minus 2.
The next number is 86.
The nth term is 22n and so the next number will be 5*22 = 110
Any number that is not 1, 2, 11 and 22
1 and 2
1, 2, 11, and 22
There is no such number. Any prime number raised to the third power has exactly four factors. For example, 23 = 8; its factors are 1, 2, 4, 8 (1, 2, 22, 23). Since - as is well-known - there is no largest prime number, there is no largest number that has exactly four factors.
The next number in the series 1 2 4 8 10 20 22 is
22
25-1=24 24-2=22 22-3=19 19-4=15 15-5=10 The next number in the series is 10.
46 would fit, double and add 2...
22
22 (2+2=4x2=8+2=10x2=20+2=22
The next set in the pattern would be 5 to 22. The pattern is to increase the first digit by 1, second digit by 2.
To find this, you can just find the factors of 22, which are 1, 2, 11, and 22.
The next number is 4, followed by -2
22.5 = 22 + .5 = 22 + 1/2 = 22 1/2
There does not appear to be a missing number. The sequence is n2 + 1. 12 + 1 = 2 : 22 + 1 = 5 : 52 + 1 = 26 : 262 + 1 = 677. The next number in the sequence is 6772 + 1 = 458330.
