Question

2/30
600, 550, --------, --------, 400, 350, 300, 250, 200

1. 500, 450
2. 500, 400
3. 350, 500
4. 450, 500

Explanation:

Step1: Identify the pattern

The sequence is decreasing. Let's check the difference between consecutive terms. From 600 to 550, the difference is $600 - 550 = 50$. From 400 to 350, $400 - 350 = 50$, and so on. So the common difference is -50 (decreasing by 50 each time).

Step2: Find the first missing term

After 550, subtract 50: $550 - 50 = 500$.

Step3: Find the second missing term

After 500, subtract 50: $500 - 50 = 450$.

Answer:

1. 500, 450
