Number stairs

The number stairs coursework involves using a 10x10 numbered grid up to 100 using this grid, i will draw on step shapes the step shapes that will be created overlap the numbers in the grid. The overlapped numbers will be added up to

Conclusion

formula must use algebra and be able to produce the answer of total sum without the use of the diagram apart from the number of stairs and the number of the bottom the bottom left square. This number will be called n in the formula.

This is because all the stair values in a 3-step stairs added together on a 15 by 15 Number grid gives 70 but when I use my formula I get 66. This means I need to increase n, and I can start this by 4 for example (n+4)

2. ## For other 3-step stairs, investigate the relationship between the stair total and the position ...

of the grid numbers: * The step stairs, regardless to whether it is a 3-stepped, 4-stepped, or 7-stepped etc or where its position is in a numbered grid, i.e. 10x10, or 21x21 etc the general formula will always give the total of the gird numbers in that step stair.

am going to the 4 step stair investigation on the 9x9 grid. 28 19 20 10 11 12 1 2 3 4 Stair number (N) =1, stair total=1+2+3+4+10+11+12+19+20+28= 110 Stair number (n) = 2 Stair Total = 2+3+4+5+11+12+13+20+21+29= 120. Stair number = 3 Stair total = 3+4+5+6+12+13+14+21+22+30= 130 Stair number=4

2. ## Staircase Coursework

I now have to multiply "n" (stair number) to the formula because according to the relation of the number in the staircase, every square contains a stair number, which would be as follows. n+3g n+2g n+2g+1 n+g n+g+1 n+g+2 n n+1 n+2 n+3 So I get the first part of the formula!!!

I can therefore conclude that the general equation for a 3-step stair on a 10 by 10 number grid is 6n + 40 = stair total where n is the base number. (Shaded box). Total of step containing 1 as its base number - Difference = 50 - 6 =

This is because not all of the position can be used as some numbers on the grid cannot be reached. Prediction I predict that there is going to be a pattern between the position of the 3-step stair and the total of the numbers inside it. • Over 160,000 pieces
