What is the sum of the arithmethic means between 7 and 25?

The only arithmetic mean of 7 and 25 is (7+25)/2 =16. If you really mean all arithmetic means of all possible pairs of numbers between 7 and 25, then there are so many pairs you should clearly state so in your question. Or better still, just write them down, work them out and add them up, which is what I would have to do.


How do you get the sum of the first 25 numbers by a means other than adding?

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.

The answer to this question Find the sum of the first 25 elements what series -5 19 43 67?

-5 19 43 67 ...This is an arithmetic sequence because each term differs from the preceding term by a common difference, 24.In order to find the sum of the first 25 terms of the series constructed from the given arithmetic sequence, we need to use the formulaSn = [2t1 + (n - 1)d] (substitute -5 for t1, 25 for n, and 24 for d)S25 = [2(-5) + (25 - 1)24]S25 = -10 + 242S25 = 566Thus, the sum of the first 25 terms of an arithmetic series is 566.

How do you find the percent of 25 percent of 200?

A percentage is a number divided by 100, so 25% is 25/100 The word "of" in mathematics means "multiplied by" So if we have 4 groups of 5, that means 4x5. In this case, 25% of 200 means 25/100 x 200 If you complete that sum, you get the answer 50.


What is the sum of odd numbers from 1 to 100?

Using the formula for the sum of an arithmetic sequence;Sum = 1/2*n [n is the total number of terms] *(2a [a is the value of the first term] + (n-1) * d)[d is the common difference between each term]So the formula looks like this: Sum = 1/2*n (2a+(n-1)*d)n = 50 because there's 50 odd numbers in a hundred and 50 even numbers (50+50=100)a = 1d = 2So inputting the values gives:Sum= 1/2*50 (2*1+(50-1)* 2)Sum= 25*(2+49*2)Sum= 25*(2+98)Sum= 25*(100)Sum= 2500Answer= 2,500
