You can search for such sequences on your favorite web search engine and you'll usually end up on OEIS.org. In this case, here: https://oeis.org/A007051
Your equation is (3^n + 1)/2.

mission_id: a498094578a
mission_id: a493453456
mission_id: 498343454a
mission_id: 34534535345
From the above 4 mission_id's I need your help in writing a regex pattern which covers all the four mission_id but need to select only the numbers.
So one the first one - need to exempt 'a' and only the numbers.
mission_id:\s*\w?(\d*)\w?
That should work; maybe add any flags you need for parsing multiline text or whatever.
www.regexr.com is a great resource for trying out RegExps

I would like to be able to convert a string such as "(5+6)*6" and get the resulting integer from that equation. It is important that it starts out as a string.
You can use library fastmathparser for c++.
In link is example how use this library.
If you really want write alone this parser, I recomended use Shunting-yard algorithm

I've developed a MATLAB code that I think it is useful to be used by researchers. How can I embed it in a website to be used free?
It gets two integers and return a set of integers
Also it is possible to convert it to c++, If it helps.
Thanks
