Answer:
The correct answer is - 768.
Step-by-step explanation:
The given question is based on a specific pattern present in between the numbers in the given series -
Series = 25 50 99 196 388
to find - next number in series
let us find the relation between the initial two number:
25 - 50, here number 50 is two times of 25 or (x*2-0)
relation between 2nd and 3rd number:
50 - 99, here 99 is two times of 50 minus 1 or (x*2-1)
relation between 3rd and 4th number:
99 - 196, here 196 is two times of 99 minus 2 or (x*2-2)
relation between 4th and 5th number:
196 - 388, here 388 is the two times of 196 minus 4 or (x*2-4)
So on this pattern, the next number would be = x*2-8
388*2-8
= 768

Answer:
3.28
Step-by-step explanation:
find the mean of all the numbers
3 + 8 + 10 + 12 + 15 = 48
48/5=9.6
so the mean of all the numbers is 9.6
now subtract 9.6 from all the numbers
|3 - 9.6| = 6.6
|8 - 9.6| = 1.6
|10 - 9.6| = .4
|12 - 9.6| = 2.4
|15 - 9.6| = 5.4
Find the mean/average of the new values
6.6 + 1.6 + .4 + 2.4 + 5.4 = 16.4
16.4/5 = 3.28
