In an arithmetic sequence, the next term is found by adding a constant term to each number to arrive at the next number. The common difference can be found by subtracting the first term from the second term.

-8.6, -5.0, -1.4, 2.2, 5.8....the common difference here is 3.6
-8.6 + 3.6 = -5.0
-5.0 + 3.6 = -1.4
1.4 + 3.6 = 2.2
2.2 + 3.6 = 5.8
so this IS an arithmetic sequence.

2,-2.2, 2.42, -2.662, 2.9282...there is no common difference..so this is not an arithmetic sequence

5,1,-3,-7,-11....common difference is -4
5 + (-4) = 1
1 + (-4) = -3
-3 + (-4) = -7
-7 + (-4) = -11
this IS an arithmetic sequence

-3,3,9,15,21...common difference is 6
-3 + 6 = 3
3 + 6 = 9
9 + 6 = 15
15 + 6 = 21
this IS an arithmetic sequence

-6.2, -3.1, -1.55, -0.775, -0.3875...this is not an arithmetic sequence

Find the median of the data. <br><br> 24,74,61,29,38,27,68,54
Nataly_w [17]

Answer:

The median of the data is 46.

Step-by-step explanation:

Put the numbers in order so it would look like this.

24, 27, 29, 38, 54, 61, 68, 74

The ones in the middle would be the mean, however, there are two numbers in an even-number data, 38 and 54.

Add these two numbers together to get 92 and divide that number by 2 to get your median which is 46.
