If the 10th of the 10 consecutive numbers is 10, what is their sum?

The sum of the number is 55.

The sequence is a list of objects which have been ordered in a sequential manner, such that each member either becomes before or after. A series is a sum of sequence terms.

Given

10th of the 10 consecutive numbers is 10.

To find

The sum of all these numbers.

We know the last number is 10.

let the first number be x

then tenth number will be x + 9

Then equate the tenth term

x + 9 = 10

     x = 10 - 9

     x = 1

Then the other number are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

Then the sum is given by

Here n is the last number

Thus the sum of the number is 55.
