Hi guys

I hope you will like being here :)

To answer your question, Adi is Karthiks twin brother. Parikshit and Gayatri actually had four kids but ended up giving one away to Gayatri's sister-in-law who could not concieve and desired to have a kid, so only three kids grew up with Parikshit and Gayatri, they being, Karthik, Shubh and Suhana.

Hope that helps you understand.
