Average of 2 numbers

What's the average of 10 and 350? 180? Wrong.
Hint/s:
a) You don't need to be a stat/math person to figure this out
b) see 'Avoiding Statistical Pitfalls' - Christopher Chatfield. Statistical Science, Vol 6, No.2 (Aug., 1991), pg. 242
c) Send me an e-mail or drop a comment here

I don't get it. Unless my education has been woefully incorrect (and I wouldn't put it past NCERT and CBSE) isn't average defined as

x-bar = (summation (xi))/n

So isn't it 360/2 = 180?
