Answer:
The given sequence 6, 7, 13, 20, ... is a recursive sequence
Step-by-step explanation:
As the given sequence is
![6, 7, 13, 20, ...](https://tex.z-dn.net/?f=6%2C%207%2C%2013%2C%2020%2C%20...)
- It cannot be an arithmetic sequence as the common difference between two consecutive terms in not constant.
As
, ![d = 13-7=6](https://tex.z-dn.net/?f=d%20%3D%2013-7%3D6)
As d is not same. Hence, it cannot be an arithmetic sequence.
- It also cannot be a geometrical sequence and exponential sequence.
It cannot be geometric sequence as the common ratio between two consecutive terms in not constant.
As
,
, ![r = \frac{13}{7}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B13%7D%7B7%7D)
As r is not same, Hence, it cannot be a geometric sequence or exponential sequence. As exponential sequence and geometric sequence are basically the same thing.
So, if we carefully observe, we can determine that:
- The given sequence 6, 7, 13, 20, ... is a recursive sequence.
Please have a close look that each term is being created by adding the preceding two terms.
For example, the sequence is generated by starting from 1.
![{\displaystyle F_{1}=1](https://tex.z-dn.net/?f=%7B%5Cdisplaystyle%20F_%7B1%7D%3D1)
and
![{\displaystyle F_{n}=F_{n-1}+F_{n-2}}](https://tex.z-dn.net/?f=%7B%5Cdisplaystyle%20F_%7Bn%7D%3DF_%7Bn-1%7D%2BF_%7Bn-2%7D%7D)
for n > 1.

Answer:
it would be 12 righhht?? because if each bunch is 6 and she has 2 bunches you would add 6+6 and get 12!! i thinkkkk or multiply :))

➷ speed = distance / time
Rearrange this for time
time = distance/speed
time = 190/40
time = 4.75hrs

Answer:
24
Step-by-step explanation:
since these are fairly small numbers it's easier to figure out. for each number just think of the 2 closest perfect square, for 10, the 2 closest perfect squares are 9 & 16, which means square root of 10 is more than 3 but less than 4,
14 also has the same perfect squares as 10, so 10&14 aren't possibilities
the closest perfect squares to 24 are 16 and 25
the square root of 16 is 4 and the square root of 25 is 5
that means root 24 is between 4 and 5
if you're confused just ask me & i'll try to explain it a different way ♡
