Very confused on how to write this program ?

Question

Hi, Im freaking out because Im not sure how to write this program. :

 

Use a for loop to compute the following sequence of numbers that are an
approximation of √
2. The sequence depends on a starting value x0 = 1. The following values
in the sequence are then calculated as follows:
xi+1 = xi/2 + 1/xi
. (1)
For example x1 = 3/2 and x2 = 17/12. The program has to compute n terms of the
approximation, where n is the Byte variable set by the user. The last term xn is then
displayed in the Label control.

 

I have no idea how to write such a program when sequences are involved! So far all I know is doing simple calculators that add/multiply numbers. Please help !!

Answer 1

Your program just needs to follow the formula given, which is just multiplication, division and addition.
