Which of the following is generated by the formula, a = 2n - 4? a. arithmetic sequence b. hyperbolic series c. limited series d. geometric sequence

Correct Ans: Arithmetic Sequence

Using n=1, we get:


Using n=2, we get:


Using n=3, we get:


Using n=4, we get:


If terms are: -2, 0, 2, 4, ...

If we observe the terms we find that each term is 2 more than the previous term. This is a property of Arithmetic Sequence.

Therefore, correct ans is option A. Arithmetic sequence
