Answer:
20 is one possible answer
24 is another possible answer The question is ambiguous
Step-by-step explanation:
First put what you have in order. The median is the central number.
12 18 22 26 30
The median for this case is not listed in your answers. 22 is not there.
So we have to give some thought to what the sixth number was. Unfortunately that leads to two possible answers
If the missing number is less than 12, the the median will be between 18 and 22. Say the missing number is 10
10 12 18 22 26 30
(18 + 22)/2 = 20 would be the answer.
However if the missing number was greater than 26 (say it was 32) then the numbers would be
12 18 22 26 30 32 the average between the 3rd and 4th numbers.
(22 + 26)/2 = 48/2 = 24
Both answers are possible and are listed. There is no single answer.
Your answer is A) 34.
A rectangle has four sides as you know.
If you use 34 as your width, both sides for width would total 68.
Then, same steps as before, accounting for both length sides by multiplying 68 by 2 and get you’d get 136.
68 (both width sides) + 136 (both length sides) would get your total of 204.

The correct answer is A. NGNGATo find a sequence is arithmetic, we are going to find its common difference:
where
is the common difference
is the current term in the sequence
is the previous term in the sequence
To find if a sequence is geometric, we are going to find its common ratio:
where
is the common ratio
is the current term in the sequence
is the previous term in the sequence
