RE: Maths Brain Teasers 66:: Can You Complete The Pie???

so the upper left quarter adds up to 14, then the lower left adds up to 23 which is 9 more and the lower right adds up to 28 another increase of 5. So let's deduct a pattern here.. step 1 = 9, step 2 = 5 step 3..

Yeah, @definethedollar got it right it's 6 and has nothing to do with the quarters! Hope there's more challenge for the next one ;-)
