Some SeqFans may already be acquainted with a weekly column entitled
Varsity Math, published Saturdays in the Wall St. Journal's Review
section.
The second ot two problems in today's edition is called The Missing
Element and reads as follows:
The open-ended sequence ...35,45, 60, q, 120,180,280, 450, 744, 1260,...
has an undisclosed element, q. Find a simple continuous function to
generate the sequence and compute the surprise answer for q.
I did a search for any sequence that contains 35 45 60 120 180 280 450
744 1260.
Seqence A103252 contains each value except 744. No sequence contains
all 9 values.
I'm guessing this sequence, once found, will make its way into OEIS.
Enjoy!
