k.m  (11 years ago)

i think in this series we need to divide series in two parts i.e in terms of even place term and odd place term.i.e
1,7,13 so in odd term you see a difference of 6.
and in even terms there is difference of 8
3,11 so next term will be 11+8=19.
so series is like this
1,3,7,11,13,19.
