More than 40 people attended where only 24 places were arranged.

So, there were some people on the floor and others by the walls.

The organizers asked of there is a chance for another workshop immediately

but I wasn’t prepared with the materials.

May be next year… ]]>

The first sum would be, 1,3,4,6,7,9,10,12,13,15,… 2nd sum chain is. 1,4,8,14,21,30,40,52,65,80,… and 3rd sum is 1,5,13,27,48,78,118,170,…which is the sum sequence from n=1 to any whole number.

Also, from this we can formulate a general formula of Se= (1/8)(n)(n+2)(2n+1) for even and So= Se-(1/8) for odd.
