VB.net Question, i want the steps espeacially the reversal and where i should code it in my vb

As an example, if the starting point of the series is 0 and 1, the Fibonacci series
is as shown below;
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, ………….nth term.
You are required to write a Visual Basic.Net program that allows a user to enter the first two terms and
the number of terms of the series. Using the first two terms and the number of terms, your program
should be able to generate the Fibonacci series up to the nth term and load the generated series onto a
combo box and also load the reversal of the series onto another combo box. Your program should further
read the series into an array. In addition, it should be able to return the middle term (median) and sum
of the series.
