What are the first three terms of the sequence represented by the recursive formula an=n^2-an-1 if a5=14 1/4
Answers
Answer:
B. 0.25, 3.75, 5.25
just convert what the person above said but into decimals
Answer:
1/4, 3 3/4, 5 1/4
Step-by-step explanation:
Solving for a[n-1], we get ...
a[n-1] = n^2 -a[n]
Then ...
a[4] = 5^2 -a[5] = 25 -14 1/4 = 10 3/4
a[3] = 4^2 -a[4] = 16 -10 3/4 = 5 1/4
a[2] = 3^2 -a[3] = 9 -5 1/4 = 3 3/4
a[1] = 2^2 -a[2] = 4 -3 3/4 = 1/4
Then the first three terms are a[1], a[2], and a[3]:
1/4, 3 3/4, 5 1/4

The length of the rectangle is 106 meters.
Further explanation
A rectangle is a quadrilateral with four right angles. It can also be defined as an equiangular quadrilateral, because equiangular means that all of its angles are equal. A rectangle can also be defined as a parallelogram containing a right angle.
Whereas the square metre (or square meter) is the SI derived unit of area thar has a symbol sq.m
Length is describes how long something is, while width is describing how wide an object is. It also defined that length pertains to the longest side of the rectangle while width is the shorter side
A rectangular playground has an area of 3,392 square meters. If the width of the rectangle is 32 meters, find the length.
By dividing area of rectangular playground by the width of the rectangle we get:

1. Minimum = 4
2. First quartile = 6.5
3. Median = 13.5
4. Third quartile = 19
5. Maximum = 20
Explanation
To calculate the measure of central tendency, you first arrange the set of the data in ascending order.
The set of data given will be;
4, 4, 9, 9, 18, 18, 20, 20.
Part 1:
The minimum value of the data is 4.
Part 2:
The first quatile is the median of the lower half which is comprised by:
4, 4, 9, 9
1st quartile = (4+9)÷2
= 13÷2
= 6.5
Part 3:
Median of the data is;
Median = (9+18)÷2
=27÷2
= 13.5
Part 4:
3rd quartile is the median of the upper half which comprises of;
18, 18, 20, 20.
3rd quartile = (18+20)÷2
= 48÷2
= 19
Part 5
The maximum of the set of data is 20.

C), D) and E)
Step-by-step explanation:
First let's see what an arithmetic sequence is.
A arithmetic sequence is series of numbers where the difference between the successive terms must be a constant.
For example,
2, 4, 6, 8, 10.....
If you find the difference between the successive terms, it will be the same constant.
4 -2 = 2
6 -4 = 2
8 -6 = 2
This is called arithmetic sequence.
A and B are not the arithmetic sequence. The different is not the same constant.
C) 345, 346, 347, 348, 349....
Difference = 1 between the two successive terms.
So it is an arithmetic sequence.
D) 54, 71, 88, 105, 122...
Difference = 71 - 54 = 17
88 - 71 = 17
So it is an arithmetic sequence.
E) -3, -10, -17, -24, -31...
Difference = -10 -(-3) = -10 + 3 = -7
Difference of -10 and -17 is -17 -(-10) = -17 +10 = -7
So it is an arithmetic sequence.
Answer: C), D) and E)
A:no
B:no
C,D,E :yes
All you have to do : is the difference of next term and the term must be constant.
if A( -3, 8 ) and B( -7, -6 ).
