It could be 11.
+4, -3, +5, -2, +6, -1, +7
1, 2, 3, 4, 6, 12 1, 2, 3, 4, 6, 12
Anything divided by one is the original number.
12 = 2 x 2 x 3
2 x 2 x 3 is the prime factorization for 12.
3 is prime number otherwise 12 has 1 12 2 3 4 6 24 has 1 24 2 12 3 8 4 6
The number that comes next in the series 1 2 2 5 3 10 is 7. You get this number by subtracting the number 3 from the number 10.
7.
11
3. 3
36, possibly. The sequnce being *2, *2, -6, *2, *2, -6 etc
If you are talking about factors, which are the multiple pairs of a number. The factors of twelve would be 1 and 12, 2 and 6, and 3 and 4
2/3 of 12 = 12*2/3 = 8
212, 213 Because, you have 2 and 3, then 12 (which is 4 multiplied by the previous number) and 13, then 52 (which is 4 multiplied by the previous number) and 53. 53 x 4 = 212.
The prime factorization for the number 12 is: 2 x 2 x 3
the number 2 in the nuber that comes after 1 and before 3.
The least number that has 2, 3, and 4 as factors is 12.
12 12/2 = 6 12/3 = 4
