19. 1 + 2 + 4 + 8 + 16 + is an example of which of the following types of series?
- Harmonic series
- Convergent series
- Arithmetic series
- Geometric series
Answer
The correct answer is: D) Geometric series
Explanation
A geometric series is represented by the series 1 + 2 + 4 + 8 + 16 + ... Each term in a geometric series is obtained by multiplying the previous term by a constant value known as the common ratio. The common ratio between consecutive phrases in this situation is 2 because each term is created by multiplying the previous term by 2.
1 × 2 = 2
2 × 2 = 4
4 × 2 = 8
8 × 2 = 16 and so on.
