Introduction In this project I am going to investigate the relationship between different stairs placed in different places in a number square, which is numbered from one to one hundred. I will be trying to find a formula to get a total of any stair any place. Example 91 92 93 94 95 96 97 98 99 100 81 82 83 84 85 86 87 88 89 90 71 72 73 74 75 76 77 78 79 80 61 62 63 64 65 66 67 68 69 70 51 52 53 54 55 56 57 58 59 60 41 42 43 44 45 46 47 48 49 50 31 32 33 34 35 36 37 38 39 40 21 22 23 24 25 26 27 28 29 20 11 12 13 14 15 16 17 18 19 20 1 2 3 4 5 6 7 8 9 10 This is a 3-step stair The total of the numbers in side the stair is 25+26+27+35+36+37+45=194 I will start on a 2-step stair 38 28+29+38=95 28 29 37 37+27+28=92 27 28 36 36+26+27=89 26 27 I have found out that every time you move the two-step stair one to the left the product of the two-step stair goes down by three. This also means that every time you move the two-step stair one to the right the product will go up by three. 23 23+13+14=50 13 14 33 33+23+24=80 23 24 43 43+33+34=110 33 34 I have found out that when you move the stairs up by one the product of the two-step stair goes up by 30. This also means that when you move the two-step...
