Answer:
.
Step-by-step explanation:
We are given a geometric sequence { -16, 4, -1, .... }
i.e. , , , ...
We will first find the common ratio 'r'.
Now,
i.e.
i.e.
i.e.
Similarly, i.e.
i.e.
So, we get that the common ratio is .
Now, the recursive formula for the geometric sequence is given by,
i.e.
i.e. .
Hence, the recursive formula for this sequence is .
Dunno the question... But I sure hope if you jump out of a plane the parachute is ALREADY inspected :d
C. only line u and line v
The mean is 76.4.
The median is 72.
Mean: 70 + 72 + 99 + 72 + 69 = 382
382 divided by 5 is 76.4.
Median : Order the data set
69, 70, 72, 72, 99
The median is a better description because in the data set there is an outlier (99).
Hope this helped! :D
