natima [27]

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:

6-2=4

10-6=4

15-10=5

Since 4\neq 5, therefore the given sequence has no common difference. It means it is not an arithmetic sequence.

Ratio of consecutive terms are:

\dfrac{6}{2}=3

\dfrac{10}{6}=\dfrac{5}{3}

Since 3\neq \dfrac{5}{3}, 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.
