Is there an easy way to make the equation centered in this:

\[x_i = y_i \hspace{1.0em}(i=1,\dots,n)\]

The parenthetical information would be off to the right.

    You might make the parenthetical information, together with the quad, zero wide; but why? The condition is part of the formula. By the way, \hspace{1.0em} is the same as \quad – egreg Jan 9 '17 at 10:11

Yes, with mathtools:

\[x_i = y_i \mathrlap{\quad(i=1,\dots,n)} \]
  • This answer gives the code for \mathrlap for those that are interested (I prefer to avoid using a whole package if all I need is one command, which I stick in my preamble instead). – Bill Wallis Jul 4 '18 at 13:00
  • Sure, but mathtools is anyway a highly recommended package, which adds many useful features to amsmath. – Bernard Jul 4 '18 at 13:05
