Can you indicate the programming language? it could be easier to help you. However, as I can see, your example presents odds numbers. So, you can use this formula:

a(n) = 2n+1

Where n are integers from 0 to the wanted size of the array.

Im using c++ .can u suggest a c++ code to automatically store values like

int a={1,3,5,7,9,11...............................} (upto 100 values.

int array[100] = {};

for(int i=1; i

yes ! 

Thankl you so much :)

very helpful.
