R.RAVIKUMAR 11 years AGO

It's can divide into two sequences by alternative positions... 24,33,51 and 30,39,?
the difference between 1st and 2nd number is 9 in each sequence..
i.e. 33-24=9 and 39-30=9
the difference between 2nd and 3rd number is 18 in each sequence..
i.e 51-33=18=> 39+18=57..

ALOK KUMAR NAYAK 11 years AGO

I think there is two sequence a={24,33,51,...} and b={30,39,...}

a = {24,24+9,33+18,51+27,78+36,...}
= 24+9⋅{0,1,3,6,10,...}
so, a= {24,33,51,78,114,...}

b = {30,30+9,39+18,57+27,...}
= 30+9⋅{0,1,3,6,...}
so, b= {30,39,57,84,120,...}

putting a & b sequence together we get--

c= {24,30,33,39,51,57...}

so, answer is 57
