how would i find the function? The series is 1,2,2,3,3,3,4,4,4,4 and so on with there being n number of the term n. How would i make a function to find the nth term?
Grateful for help.
First you have to know that
for every n integer such as
n being given, to find k you must have both inequations
and are parabolas with the same discriminant 8n+1
There is only one integer k satisfying these inequations because
