MATLAB: Artificial Neural Network prediction

I am Sumit Kumar Ghosh. I have a question regarding prediction by Artificial Neural Network.

If I want to predict that what will be the value of ph in 2020. What I have to do in Artificial Neural Network?

Data:

x= Ph; which range is 0 to 14.

Lets,

x=[ 6,5,8] y=[ 2014,2016,2017]

I have to find what will be the value of x in the year of 2020 by the Artificial Neural Network.

I can't find any perfect solution. Will you please help me?

Sincerely, Sumit Kumar Ghosh

The data set doesn't have the information for predicting anything specific.

Predictions are based on a history of variations of one or more quantities. You only have 1 point for each quantity.
