Given:
The sequence is:
2, 6, 10, 15,...
To find:
Whether the given sequence is Arithmetic, Geometric, Neither.
Solution:
We have,
2, 6, 10, 15,...
Different between consecutive terms are:



Since
, therefore the given sequence has no common difference. It means it is not an arithmetic sequence.
Ratio of consecutive terms are:


Since
, therefore the given sequence has no common ratio. It means it is not a geometric sequence.
Since the given sequence is neither arithmetic nor geometric, therefore the correct option is C.
First let's find out the total number of strikeouts, by adding the number of strikeouts of each person:

Now, to find the percentage of strikeouts that Samar is responsible, let's divide his number of strikeouts (5) by the total number of strikeouts (50):

So Samar is responsible for 10% of the strikeouts.
.5X+3.50y=33.50 Would be the equation hope this helps
