Question

Please help me with these two questions

The median of a set is not affected by outliers.

True
False



Which of the following sequences is not an arithmetic sequence?

0, -2, -4, -6, ...
1, 5, 9, 13, ...
15, 12, 9, 6, ...
-1, -2, -4, -8, ...

Answer 1

The median isn’t affected much by one outlier.

sequence: -1,-2,-4,-8 is not arithmetic it is geometric

Answer 2

True

-1, -2, -4, -8, ... is the non-arithmetic sequence. It’s geometric as there’s a common ratio of 2.
