Answer:
The sixth number in series is 13.
Step-by-step explanation:
Given series : 3, -6, 12, 4, 20, ?
The pattern followed by the series is:
The first number = 3
Second number = 3 - 9 = - 6
Third number = - 6 + (9 ×2) = -6 + 18 = 12
Fourth number = 12 - 8 = 4
Fifth number = 4 + (8 ×2) = 20
Sixth number = 20 - 7 = 13
Seventh number = 13 + (7 ×2) = 13 + 14 = 27 and so on.
So as per the above pattern, the sixth number in the series is 13.
The square root of 110 is 10.49. Hope this helps you!
The question requests proof that WV = VR. See the definition of Mathematical proof and the explanation for the proof below.
<h3>What is a mathematical proof?</h3>
Mathematical proof refers to the steps of logical arguments which are given to show that a mathematical statement is true or correct.
<h3>What is the proof that WV = VR?</h3>
Reason: This is given. The image is a parallelogram.
- Hence, ∠PSR = ∠WVP
Reason: Alternate angles formed by two parallel lines crossing each other
Hence, SV = PVReason: This is given by the annotation on the image
- Reason: They are formed by two parallel lines crossing each other.
Therefore if ΔSVR ≅ PVW;
Then WV = VR.
