You use that equation to add up the numbers from a starting value to the last value.
"n" is the amount of terms, "a1" is the first term and "an" is the nth term, meaning it's the 64th number in the sequence.
So it would be
sum = (64(48 + 432)) / 2 which is 15360.
Is that right? Lol it's been about a year since I took advanced maths.

right?
The rest of your equation are barely right.
I doubt your manner to find result of "an".
Make sure to find the determinant of "Tn' first.
Here the equation.
Then multiply the result to your own equation.
Even if you answer it correctly, you didn't won anything.
'Nuff said.
Someone already answer it in previous page.
But he didn't outlined his own equation.
So we're still waiting.
〖64〗_(n=) (64(〖48〗_1+〖426〗_n))/2=15,168
I had to go into word for this but, its arithmetic sequence i have to find the sum of 64 terms so i put 64 over n equals to 64 times 48 plus 426 dived by 2 which equals to 15,168. I first added 48 and 426 together then i got 474. 474 times 64 equals to 30,336. Half of that is 15,168
Also sorry i dont know how to paste my equation from word exactly like it is to here

Yes, this is the correct result.
Your prize will be sent later once i got unbanned.
I hereby announce that this week prize are claimed by Uhhwat's!
Congrats!
For anyone who work harder but didn't win the prize, don't worry!
I'll appreciated all your hardwork.
Just stay tuned and wait for amazing prize next week!
Also for those who still confused with his equation, there are simple manner.
First of all, we've to find determinant of Term/I.
I = a + (n - 1) x d
=48 + (64 - 1) x 6
=426
Next, integrate the result and multiply them with
last equation.
s = n/2 (a + I)
=64/2 (48 + 426)
=15, 168

I think that is right. Right?
Sorry.
His answer and equation are most accurate.
Moreover he was answer first correctly (check previous page).
