Im creating a website about Universities , and they usually have a threshold for accepting students each year , it usually depends on the numbers of seats available , the number of contestants ...etc
What im trying to do is predict the next threshhold based only on the previous threshholds .
For example : the thresholds for the previous years are the following in order : 14 , 14.5 , 16 , 15.25.
What is the simplest way to predict the next one based on the way the treshholds were going up and down?
I'm very close to the deadline and I have just realized ( thanks to the folks here ) that my previous method only used the first and last threshhold . Thanks in advance .
