The random number I have chosen is 69; this will be the t-number for checking my formula. I am now going to substitute the number into the equation:
T-total = 5(69)-63
T-total = 282
Now that I have got my prediction I will do what I have done for all the other numbers and find it out manually.
Predicted number:
The t-number in this case will be 69.
The t-total is 69+60+51+50+52 which will
give us 282.

Grid 2: (10 by 10)
Secondly I have chosen to look at the 10 by 10 grid. I will be taking five t-numbers in a row and investigating the t-totals for them. Once I have completed all five, I will then look for a formula to link those five and then I will be moving onto the third grid.

I will then add up the t-total and if it matches my prediction my formula will be correct.

Conclusion:
After carefully examining each formula carefully I have come up with a formula that will link any t-number on any grid to its t-total. I firstly collected all the formulas for the grids and put them in this table:
The first thing I noticed when I looked at this table that every time the grids size was increased by one, the number taken away from 5n in the formula increases by seven.
I also noticed that the number taken away from 5n is the same as seven multiplied by the grid number every time, so 9 would be 63, 15 would be 105 and so on.
By figuring this out I managed to make a formula linking the t-number of any grid to its t-total using a quick simple formula. The formula is as follows:
T-total = 5n-7g
N=the t-number
G= the grid number
Now I will simply try the formula out on a random t-number chosen on a random grid and see if my formula works out correctly.
The random t-number I have chosen is 109 from the grid 11 by 11. I am now going to substitute these figures into the equations I have got and predict the t-total without adding the numbers. I will then check my prediction and if it matches the answer I add up I will know that my formula is correct.
Prediction:
T-total = 5n-7g (n=109 , g=11)
(5*109) - (7*11 545-77
My prediction is that the t-total for t-number 109 is going to be 468. I will now check to see if my answer is correct.
Check formula:
The t-number in this case will be 109.
The t-total is 109+98+87+86+88 which will
give us 468.
T-number: 109
T-total: 468
My formula is correct; I have solved the relationship between t-numbers and t-totals on any sized grid. The formula (5n-7g) is the answer to this problem.
