The mean
The sum of the numbers divided by the number of numbers.
An arithmetic sequence is a list of numbers which follow a rule. A series is the sum of a sequence of numbers.
An arithmetic series is a fairly similar to an arithmetic sequence except for the fact that in a series you are adding the numbers in between, not putting commas. Example: Sequence 1,3,5,7,.........n Series 1+3+5+7+..........+n Hope this helped(:

An arithmetic series is the sum of the terms in an arithmetic progression.

That refers to the sum of an arithmetic series.

By using the formula for an arithmetic series. This is basically obtained by reasoning: The sum of the first 25 numbers is the same as 25 multiplied by the average of those numbers; the average in this case is simply (1 + 25) / 2.

Just add them together, and divide the result by 10. (For the average of a larger set of consecutive odd numbers, it's faster to use the formula for an arithmetic series to add them up. Also, the average of such a set is the same as if you just average the first and the last number.)
You can just go ahead and add them. Or you can use the formula for an arithmetic series.
Use the formula for an arithmetic series. That is, take the average of the first and the last number in the series, and multiply by 25. The first number in the series of course is 1; the last number is 1 + 2(24), since there are 24 intervals.
I believe you meant an arithmetic series. It is a series of numbers differing by a certain number from the previous number of the series. In this case, they differ by 123.
