Re: Australian Mathematics Competition
Did you misread the question? The question was not referring to the number of hexagons in pattern 11, but the number of matches/whatever required to make the pattern.
Sorry I don't really understand your working? The solution to the hexagon question was 231....I am not quite sure what number question it was, but it was a 10 mark question. It was in the intermediate division. The question was on patterns, it showed pattern 1,2 and 3 then it said what would pattern 11 be. My answer was 66, and i am very confident on that. So can anybody help me out.

What is pattern 11? That was the question im pretty sure, thank you in advanced for replys. <>=hexagon
I will try and describe how i worked it out. Pattern 1 has one hexagon, while pattern 2 has three hexagon. So if i add 2 + 1=3 i got the one from the hexagon in pattern 1 and the two from the pattern (2)<--....Pattern 3 if we add three hexagons to pattern 2 thats gives us 6 and it also gives us pattern 3. So basically the next hexagon pattern 4 i would add 4 hexagons to the previous pattern. So its basically 6 hexagons from pattern 3 so i did.....6+4+5+6+7+8+9+10+11=66
