13 10 17 15 21
13 - 10 = -3
10 - 17 = +7
17 - 15 = -2
15 - 21 = +6
The negative numbers alternate with the positive numbers
The negative numbers are augmented by +1 each step
The positive numbers are diminished by -1 each sterp
So the next step from 21 is a negative and should be -2 increased by +1 to -1 giving a new value of 20
Then the next step is a positive and should be +6 decreased by -1 to +5 giving 25
13 - 10 = -3
10 - 17 = +7
17 - 15 = -2
15 - 21 = +6
21 - 20 = -1
20 - 25 = +5

What is the median in math?
The middle number (in a sorted list of numbers).To find the Median, place the numbers you are given in value order and find the middle number.Example: find the Median of {13, 23, 11, 16, 15, 10, 26}.Put them in order: {10, 11, 13, 15, 16, 23, 26}The middle number is 15, so the median is 15.(If there are two middle numbers, you average them.
What two numbers have a difference of 3 and a product of 130?
10 and 13 have a difference of 3 and a product of 130. 13 - 10 = 3 13 x 10 = 130
What is the sum of 2 numbers is 13 and their difference is 7?
3 and 10 The sum of 3 and 10 is 13 The difference of 3 and 10 is 7 Using algebraic notation, if the two numbers are x and y: x + y = 13 x - y = 7 If you add these two equations you get 2x = 20 so x = 10 Substituting this back into the original equations you find that y must then be 3
Number sequence what numbers are missing 1 4 7 13?
10 (between 7 and 13)
What are the missing numbers in this sequence 4 -5 -10 -16 what are the missing numbers?
The solution depends on how many numbers are missing and where they were. If there is only one, If it is between 4 and -5 then -0.5 If it is between -5 and -10 then -8 If it is between -10 and -16 then -13 Of course, the answer would be different if there were more than one number missing.
What sum of two numbers is 7 and their difference is 13 Find the numbers?
10 + (-3) = 7 10 - (-3) = 13 10 and -3
What numbers are missing 2 4 5 7 8 10 11 14?

What is the maean?
To find the mean of two or more numbers you add all the numbers together and divide by how ever many numbers there are.Example:find the mean of the following numbers: 25, 10, 13, & 4step 1: add the numbers together 25+10+13+4=52step 2: divide the answer by 4 because you were told to find the mean of 4 numbers 52/4=13step 3: the answer is 13
Find the mean of the set of numbers 13 2 15 10 5?
The mean of a set of numbers is defined to be the quotient of the sum of all the numbers divided by how many numbers are summed. In this instance, (13 + 2 + 15 + 10 + 5)/5 = 9.
Find two numbers whose product is 30 and whose sum is 13?
10 and 3
What is the mean of 20 10 13 20 9 6?
To find the mean, you first add up all the numbers.20+10+13+20+9+6=78Then, you divide by how many numbers there are.78/6=13The answer is 13.
What is the point of the Pythagorean theorem?
to find if the triangle is right or find missing angles. Ex: a2+b2=c2. Lengths of a triangle are 13, 10 and X. 13 is the hypotenuse so you plug it into the c2 part
How do uu find the mean?
To find the mean you first have to add up all the numbers then you divide it by how many numbers you have and you got the mean. Example: 12+13+5=30 30/3=10 10 is the mean
