Answer / grs

If we consider the set of odd numbers
1,3,5,7,9,11... as x1,x2,x3,x4,x5,x6....

and the expression(Xi*Xi+1)+2

(1*3)+2=5
(3*5)+2=17
(5*7)+2=37
(7*9)+2=65
(9*11)+2=101

If the question was like this -> 5,17,37,65,101.... i.e. 65
instead of 55 then the number next in the series would be
(11*13)+2 = 143
