T-Total!

I am investigating the relationship between the T-total and T-number on a variety of grids

8x8 Grid

Let T-number = n

Let T-total = T

Formula = 5n – 56

I tested that when:

n = 63

T = 259

Below is a t-shape, and in each cell how the number is connected with n on an 8x8 grid

I will now check the formula

(n)+(n-8)+(n-15)+(n-16)+(n=17)

= 5n – 56

so this is correct

9x9 Grid

Join now!

Formula = 5n – 63

I tested that when:

n = 80

T = 265

Below is a t-shape, and in each cell how the number is connected with n on a 9x9 grid

I will know check the formula

(n)+(n-9)+(n-19)+(n-18)+(n-17)

= 5n – 63

so this is correct

10x10 Grid
