With chaining a series of observables?

Question

I have to get the answer from a Observable and use it from parameter to another Observable, I’m using the operator switchMap() for that, but I don’t know if it’s the right way. Ex.:

Observable1.pipe(
switchMap(resposta1 => observable2(resposta1)),
switchMap(resposta2 => observable3(resposta2))
).subscribe(resposta3 => this.minhaVariavel = resposta3);
