"C" TOTALS INVESTIGATION WHAT IS THE INVESTIGATION ABOUT? In this investigation, I have tried to experiment using different grids but the same C shape. WHAT IS THE PROBLEM? I am going to start with a 9x9 grid with 81 counting numbers in it and write them down. I will then draw a as shown below in my mini diagram: The bottom right number is going to be my C number (n) and the total of all the numbers in the C is going to be my C total, (I am going to call this "t"). Finally, I am going to see if there is a relationship between "n" & "t". MY GRID... 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 Below I have drawn some random C's, which I took from the table. 41 42 50 59 60 N=60 T=60+50+59+41+42= 252 8 9 17 26 27 N=27 T=8+9+17+26+27= 87 56 57 65 74 75 N=75 T=56+57+65+74+75= 56 57+ 113 65+ 178 149+ 327 3 4 12 21 22 N=22 T=3+4+12+21+22= 62 From above I can see a pattern forming; the T numbers are ending in a 2 or a 7: 252, 87, 327, and 62.
