There is a logical pattern to the following series of numbers. What are the next three numbers in the series?
15 21 25 27 33 35 39 ...
I perceive a 'refletive' pattern in the intervals between the numerals.
That pattern is: [2] 6 4 2 6 2 4 6 2 4 ...
making the series:[13]15 21 25 27 33 35 39 45 47 51 ...
Well! It's logical, but does it match the logic of Gautam?
Number Series may need some guiding rules.
123.. maybe the start of 1234.. or 1235.. or 1236..
In an examination situation (eg IQ), if my set of rules work then why should I be penalised? I'm sure it happens to many genii!!
Series: 15 21 25 27 33 35 39 ...
