Hello

Additional Information for Mathematically Inclined PMs(Not saying they are generally not:-))

If Cx=no of additional channels required for x no of additional people with n no of original people
Cx=x(x+2n-1)/2
This means if one person is added then Cx=n.
So if the question says what happens if 2 people are added then
when one person is added Cx=n1,
Now at this point n2=n1+1. So if one more person is added n3=n2+1 Cn3=n2

Cameron - Rama's formula answers a different question, and seems to be correct. I backtested, and the simple formula doesn't seem to provide the same answer. E.g. "if stakeholders increased from 15 to 18, how many new channels were added?" [Ans: 48]
