If the third of 6 consecutive numbers is 12, what is their sum?

the answer is 75

75 square root of 75 squared

75 10 + 11 + 12 + 13 + 14 + 15 = ?

never mind I got it

75 Consecutive numbers mean numbers that go in order like for example 1,2,3,4,5 and so on...

in this case, it said that 12 is the third of 6 consecutive numbers meaning that it's the 3rd down the list. So it would go like 10,11,12,13,14,15. Now you add them all together getting 75

how did you get that answer?

76

-1

Did you know?

Did you know that you can find the sum of a series of consecutive numbers by using a simple formula? In this case, the third number in a series of 6 consecutive numbers is given as 12. By subtracting 1 from this given number, we can find the common difference between each consecutive number, which is 4. Using the formula for the sum of a series of consecutive numbers, which is (n/2)(first term + last term), we can calculate their sum. The first term can be found by subtracting 2 times the common difference from the given number, resulting in 4. The last term is found by adding 2 times the common difference to the given number, resulting in 20. Finally, plugging these values into the formula gives us (6/2)(4 + 20), which simplifies to 3 times 24, equaling a sum of 72.
