Find the missing value 480, ?, 120, 60, 30

Correct option is A

Given:

Sequence: 480, ?, 120, 60, 30

The pattern indicates a decreasing trend.

Formula Used:

Each term is obtained by dividing the previous term by 2:

Next Term = $$\frac{\text{Previous Term}}{2}$$​

Solution:

1. From the given sequence, work backward from the known terms:

- 120 → 60 → 30: Each step involves dividing by 2.

- To find the term before 120, multiply 120 by 2:

Missing Term = 120 × 2 = 240

2. Similarly, to verify the term before 240, divide 480 by 2:

$$240 = \frac{480}{2}$$​

Thus, the sequence 480, 240, 120, 60, 30 satisfies the rule.

Final Answer:

The missing value is 240.
