Add I to 10000,

Example Add I to 10, means 1+2+3+4+5+6+7+8+9+10=55

Tip the pattern is really simple if you can see it.

If you still cannot see it add 1 to 100,

A 5050

B 500500

C 500050000

D 5000050000

Well then let's try and find the pattern!

When we add 1 through 10, we can also say that we're adding all of these values together:

1 + 10 = 11

2 + 9 = 11

3 + 8 = 11

4 + 7 = 11

5 + 6 = 11

So we can also say that this is like multiplying 11 * 5 = 55

If we add up to 100, we can see that it's like multiplying 101 * 50 = 5050

From this, we can get an equation:

(x + 1) * (x/2)

So let's plug in 10000 into this equation:

(x + 1) * (x/2)

(10000 + 1) * (10000/2)

10001 * 5000 = 50005000

Answer:

C 50005000
