After you have gotten a girl from tinder’s number after 3-5 messages back and forth. What is the most effective way to set up a date?

My idea is: Ask her what she’s gonna be up to to the following week. She will answer something and ask about mine; I text something like: “Apart from meeting you at X place X day, something more I am going to do”.

Is this good/bad?

What are you go-to “lines”? Maybe it’s just best to say “meet me X at Y time” immediately?
