Question

Answer please!!!! :)

Answer 1

Answer:

516

Step-by-step explanation:

So this is a problem that can be solved using sequences and series.

The formula for an arithmetic sum is:

$Sn = \frac{n}{2} (2u_{1} + (n-1)d)$

Our n value or the number of rows is 24

Our first row or u1 is 10

And our common difference is 1 as 11-10 is 1

So:

$S_{24} = \frac{24}{2} (2(10) + (24-1)1)$

$S_{24} = 12(20 + 23)$

$S_{24} = 516$

I believe this is the correct method to solve this problem
