Find the next two numbers in the folowing pattern: 12,500,2500,,500,-100

PS:12,500 is pernounced Twelve thousand five hundred.

Find the mean of the folowing integers: 5,-7,12,-10,15. Also:-16,-27,21,-19,14,-3 Sorry about the extra work.

"pernounced" is pronounced "pronounced."

#1: each number is .2 times the previous one.

#2. the mean is just the sum divided by how many there are:

(5,-7,12,-10,15)/5 = 3
(-16,-27,21,-19,14,-3)/6 = -5

To find the next two numbers in the given pattern, we need to observe the pattern and identify the relationship between the numbers.

Looking at the given pattern: 12,500, 2500, 500, -100, we can see that each number is multiplied by 0.2 to get the next number. Let's break it down step-by-step:

12,500 × 0.2 = 2,500
2,500 × 0.2 = 500
500 × 0.2 = 100
100 × 0.2 = 20

So, using the pattern, the next two numbers are 20 and 20 × 0.2 = 4. Therefore, the next two numbers in the pattern are 20 and 4.

Now, let's move on to finding the mean (average) of the given integers: 5, -7, 12, -10, 15.

To find the mean, we need to add up all the numbers and divide the sum by the total number of values. Let's calculate step-by-step:

5 + (-7) + 12 + (-10) + 15 = 15
15 ÷ 5 = 3

Therefore, the mean of the given integers is 3.

For the second set of integers: -16, -27, 21, -19, 14, -3, we'll follow the same steps:

-16 + (-27) + 21 + (-19) + 14 + (-3) = -30
-30 ÷ 6 = -5

Hence, the mean of the second set of integers is -5.
