What is the range of the following numbers? 12, 20, 18,25, 6 O A. 5 O B. 16 B. 16 oc. C 18 O D. 19 o E. 25

D

Step-by-step explanation:

The range is the difference between the largest and smallest values in the data set.

Here the largest = 25 and the smallest = 6, thus

range = 25 - 6 = 19 → D

what do you need with. i love quadrants. can you tell me ?

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
