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.

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 median of 25 and 50 is also their arithmetic mean. 37.5

Factors of 25: 1, 5, 25 Their sum = 31 Difference between 31 and 8 = 23.

The sum of all integers between 1 and 25 is equal to (25 x (25 - 1))/2 = 325.

I assume the question refer to the sum of positive odd numbers up to 25. If so, the answer is 169. If not, please resubmit your question stating exactly what you require.

-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.

The sum of -5 and 20 is 15. The distance between -5 and 20 is 25. The sum of the numbers between -5 and 20 is 180. The sum of the numbers from -5 to 20 is 195.

Assuming the series is 1 + 3 + 5 + ... + 25, the answer is 169.

Add all the data together and then divide the sum by the number of data points. For example, 3, 4, 5, 6, 7 Sum is 25 There are 5 numbers or data points which combined to make that sum The mean or arithmetic average is 25/5 = 5

There is a formula to calculate this sum. It is, S = ½n(n + 1) In this question, n = 25 so the sum of the numbers from 1-25 is, ½ x 25 x 26 = 325

3665, excluding 25 and 100.

sum = 1/2 x number_of_terms x (first + last) number_of_terms = (last - first) ÷ difference + 1 = (25 - 0.5) ÷ 3.5 + 1 = 8 ⇒ sum = 1/2 x 8 x (0.5 + 25) = 102

Arithmetic

The sum of prime numbers between 1 and 25 is 100. 2 + 3 + 5 + 7 + 11 +13 +17 + 19 + 23 = 100

The numbers are 24, 25, 26, 27, 28 and their sum is 130

There are 12 even numbers between 2 and 24 inclusive.The sum is 154.

Neither.

The sum of the first 25 prime numbers is 1,060.

The factors of 25 are 1, 5, and 25 1 + 5 + 25 = 31 (the sum of all the factors of 25)

9+16+25= 50

The sum is 14913.

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.

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
