Answer:
Stratified random
Step-by-step explanation:
got it right
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.
