The fifth term in the sequence would be 161.
Step-by-step explanation:
We have to find the fifth term in the sequence
Given that
a1 = 1 (that is the first term)
If we follow the formula, the value of every term depends on the value of immediate lower term. Therefore, the a2 can be calculated by putting 2 in place of n in above equation
as a1 = 1
Similarly,
as a2 = 5
and
as a3= 17
and
as a4 = 53
Therefore, the fifth term in the sequence would be 161.

Answer:
n(B)=21.
Step-by-step explanation:
n(AUB) means the the number of elements in both A & B. And that includes the ones in common too.
n(A∩B) means the ones that in common.
n(A-B) refers to the elements that belong to A alone. That means the elements in A excluding the common elements.
n(B) is the number of elements that belong to B and that includes the common ones too.
Now coming to your question.
The total number of elements that can fit in both the sets is 36.
While the number of common elements is 16.
And also given that n(A-B)=15.
Now according to the definitions above....n(A) should include the ones that belong exclusively to A alone and also the ones in common.
So,
n(A)=n(A-B)+n(A∩B)
=15+16
=31
Therefore, n(A) is 31.
Now when n(AUB) is 36 and n(A) is 31, it is clear that the elements exclusive to B alone is 5, i.e.36-31.
Now n(B)=n(A∩B)+n(B-A)
Therefore, n(B) is 16+5 = 21.
n(B)=21.
Answer:
As per Provided Information
- Area of rectangle is 54 square inches
- Width of the rectangle is 9 inches.
We have to calculate the length of rectangle .
As we know the formula to find the Area of rectangle .
On substituting the value we obtain
<u>Therefore</u><u>,</u>
- <u>Length </u><u>of </u><u>the </u><u>rectangle </u><u>is </u><u>6</u><u> </u><u>inches </u><u>.</u>
The correct answer is:
