Answer 2

Answer:

The mean of the given sequence is A) 5.

Solution:

A sequence is the set of terms with or without exhibiting certain patterns.

It may consist of various terms either numbers, alphabets, symbols, etc.

Different means like Arithmetic, geometric, harmonic means can be calculated depending upon the sequence of entities.

Mean of any sequence is the average of all the entities.

Let us consider the given problem of sequence 4, 2, 2, 2, 5, 15.

There are 6 entities in this sequence.

The mean of the sequence is the sum of all the entities divided by the number of the entities.

i.e., $\text {Mean} =\frac{4+2+2+2+5+15}{6}$

$=\frac{30}{6}=5$

Therefore, the mean of the given sequence is 5.
