Given sequence:
.
We need to find first four terms of the sequence.
We already given first term -3.
Let us find second term .
Plugging n=2.
Now taking n=3.
.
Now, n=4.
.
We got terms -3, 2, 7 and 12.
<h3>Therefore, correct option is B) –3, 2, 7, 12.</h3>Answer: The score p81 that separates the bottom 81% from the top 19% is 80.12
Step by step:
First, calculate the "z" value. Z is a normally distributed random variable with 0 mean and standard deviation 1. The score value corresponding to the desired percentile p81 can be determined from a z value as follows:
We use a z-table (check online) to find the z value for the 81-st percentile. I found and so we use that value to calculate the score for the percentile:
The score p81 that separates the bottom 81% from the top 19% is 80.12
