How to plug my iphone into my smart tv?

I have an iphone 5. But i also have a Hisense 50" smart tv. I use pandora but not all the time because i found that 8tracks has a better list, anyways, I want to find a way to plug a chord into my phone and play it on my tv but i don't know how. What APP or CHORD do i need? I need technical help.
