Work out the mean for the data set below:
4.7, 4.2, 8.2, 9.5, 3.1

5.94

Step-by-step explanation:

To find the mean, you need to add the numbers and divide it by however many numbers you have.

4.7 + 4.2 + 8.2 + 9.5 + 3.1 = 29.7

There are 5 numbers, so divide the sum by 5

29.7/5 = 5.94

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
