212, 213
You multiply the last number by 4 and then add 1.
212 plus 1, times 4
They will turn 53 in 2017, but as of this date, they are still 52.
-52 + (-53) = -105
4 can go into 53 a total of 13 times, since 4 multiplied by 13 equals 52, which is the largest multiple of 4 that is less than or equal to 53. When you divide 53 by 4, you get a quotient of 13 with a remainder of 1. Thus, 4 fits into 53 thirteen times with 1 left over.
It is possible to produce a formula so that any number of your choice could be the next number. Using Occam's razor though, the simplest answer is 54.
212.
240
212
The pattern is: n = n + 1 n = n * 4 repeat So, 2, 3, 12, 13, 52, 53, 112, 113, 452, 453, ...
212 plus 1, times 4
The next number would be 212, because the pattern is add 1 (2->3) and times by 4 (3x4=12)... so 52 add 1 = 53, so 53 x 4 =212.
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 factors of 53 are: 1, 53 The factors of 156 are: 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
Depends: It could be -366 - if you fit a quintic polynomial to the 6 points. or It could be 212 - if the sequence is +1, *4, +1, *4 etc
