Joe| Guest July 28th, 2007 - 12:42 pmThe middle number is the average.

(3+9+2+13+8)/5=7

(21+6+13+3+9+8)/6=10

(2+16+3+9+1+8+3)/7=6

The answer is 6.

Riyad| Guest July 28th, 2007 - 6:27 pmFirst star numbers totalled 35 divided by 5 triangles = 7

Second star numbers totalled 60 divided by 6 triangles = 10

Third star numbers totalled 42 divided by 7 triangles = 6

Next # should be 6

Lykos Protogonos| Guest July 29th, 2007 - 12:33 amThe number in the last figure should be 6.

First, add up the total of the numbers of all the purple triangles for that figure. Then, divide this number by the number of sides on the inside figure.

Figure 1: 2 + 3 + 8 + 9 + 13 / 5 = 35/5 = 7

Figure 2: 3 + 6 + 8 + 9 + 13 + 21 / 6 = 60/6 = 10

Figure 3: 1 + 2 + 3 + 3 +8 + 9 + 16 / 7 = 42/7 = 6

Brian| Guest July 29th, 2007 - 8:00 amIt’s six.

Le formula:

(added value of the purple triangles) / (# of purple triangles) = center #

(sum of numbers in purple divided by number of sides of regular polygon in the middle)

Phil| Guest July 29th, 2007 - 5:03 pmI thnk the answer is 6.

The total of the numbers in the 5-point star is 35. Number of points times 7 = 35.

The total of the numbers in the 6-point star is 60. Number of points times 10 = 60.

The total of the numbers in the 7-pointer is 42. 7 times ? = 42, therefore ? = 6.

Emilie| Guest July 30th, 2007 - 12:05 amAnswer is 6. You get the middle number by adding the numbers on each leg of the star then dividing it by the number of legs.

E.g. First star – 3+9+2+13+8 = 35, 35/5legs = 7

Second star – 21+6+13+3+9+8 = 60, 60/6 legs = 10

so on and so forth.. =)

John Lewis Highsmith| Guest July 30th, 2007 - 12:48 amThe answer is 6.

Sum the values in the triangles. Divide by the number of triangles.

jason| Guest July 30th, 2007 - 7:56 amadd the numbers and divide by the amount of sides….6

farshid| Guest July 30th, 2007 - 8:16 amnumber is 7

rosey| Guest July 30th, 2007 - 8:20 amHA! This was a hard one! The answer is 6.

Here’s how it’s done: you have a 5, a 6 and a 7 pointed figure. If you add the numbers in the points on the first figure and divide by 5, you get 7. In the second figure add the numbers and divide by 6 to get 10. So in the third figure you add all the numbers and divide by 7 to get 6.

Add up all of the purple numbers, then divide by the number of points on the star to find the number that should be in the middle.

35/5 = 7

60/6 = 10

42/7 = 6

robert L| Guest July 30th, 2007 - 9:51 amOK, this might be a stretch but if you multiply the middle number by the number of sides that the inside shape has, it = the sum of the numbers around the outside. on the first one 5 inner sides times 7 (inner number) = 35 (outer number sum). Same for middle 10 (inner number times 6(inner sides) = 60 (outer number sum). So the last one = 6 because 7 (inner sides) times 6 (inner number) = 42 (outer number sides). I laugh at myself sometimes but that is the only logical thing and i think this is the answer.

robert L| Guest July 30th, 2007 - 9:52 amby the way I just got a chance to look at this puzzle like 10 minutes ago.

Ian| Guest July 30th, 2007 - 12:37 pmI got 6

ALO| Guest July 30th, 2007 - 12:52 pm6

Mark W| Guest July 30th, 2007 - 3:15 pm6

It’s the sum of the surrounding numbers, divided by the number of points on the star.

RK| Profile July 30th, 2007 - 8:39 pmThis one was kind of tough, but many still got the right answer: 6
