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.
The mean is the sum of all of the numbers in the series divided by the number of items in the series. In this case it is the SUM(10...190), which equals 1900. There are 19 items in the series, so the mean is 1900/19 = 100.

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.)

It is an arithmetic sequence. To differentiate arithmetic from geometric sequences, take any three numbers within the sequence. If the middle number is the average of the two on either side then it is an arithmetic sequence. If the middle number squared is the product of the two on either side then it is a geometric sequence. The sequence 0, 1, 1, 2, 3, 5, 8 and so on is the Fibonacci series, which is an arithmetic sequence, where the next number in the series is the sum of the previous two numbers. Thus F(n) = F(n-1) + F(n-2). Note that the Fibonacci sequence always begins with the two numbers 0 and 1, never 1 and 1.
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.
