In this question, we're trying to find the next number in the sequence.
We know that the sequence is:
-10, -3, 4, 11, ?
We're trying to find the number after 11.
To find the answer, we would need to notice how the sequence is changing.
You would notice that the sequence is adding 7 every time.
-10 + 7 = -3
-3 + 7 = 4
etc
Since we know that the numbers are increasing by 7 every time, we can get our answer.
We would simply add 11 and 7 to get our next number in the sequence.
11 + 7 = 18
The next number in the sequence would be 18
<h3>I hope this helped you out.</h3><h3>Good luck on your academics.</h3><h3>Have a fantastic day!</h3>The given sequence is not arithmetic sequence
<em><u>Solution:</u></em>
Given sequence is:
We have to find if the above sequence is arithmetic sequence or not
An arithmetic sequence is a sequence of numbers such that the difference of any two successive members of the sequence is a constant
<em><u>Here in the given sequence</u></em>
<em><u>Let us find the difference between terms</u></em>
Thus the difference between terms is not constant
So the given sequence is not arithmetic sequence
Answer:
Height of the pole = 9.17 chi.
Length of the rope = 12.17 chi.
Step-by-step explanation:
Given that the rope is hanging from the top of a pole having height x chi and the portion of the rope lying on the ground is 3 chi.
So, the length of the rope= x + 3 chi.
Let AB represents the pole in the figure, and one end of the rope is at point A.
When the rope is tightly stretched, let C be the other end of the rope as shown in the triangle.
The length of the rope = AC.
\Rightarrow AC=x+3 chi.
Distance from the bottom of the pole, point A, to the other end of the pole, point B, is 8 chi.
So, BC=8 chi.
As the triangle ABC is a right-angled triangle, so by using Pythagoras theorem,
chi.
Hence, the height of the pole, chi,
and the length of the rope, chi.
