<p>On the SAT, which of the following is better? What about in non-SAT writing?</p>
<p>(1) red, white, and blue</p>
<p>or</p>
<p>(2) red, white and blue</p>
<p>Thanks!</p>
<p>Use whichever one you prefer; they’re both correct.
The first one that you listed is mainly used in America, and the second one is mainly used in the UK.</p>
<p>My English teacher last year told us that the latter is becoming more and more used, due to the inherent redundancy of the second comma.</p>
