Answer
- Fifth line: 5 marbles
- Seventh line: 3 marbles
- Eighth line: 2 marbles
Solution
The pattern starts at 9 in the first line and decreases by 1 on each subsequent line. That gives us:
• 1st line: 9
• 2nd line: 8
• 3rd line: 7
• 4th line: 6
• 5th line: 5
• 6th line: 4
• 7th line: 3
• 8th line: 2
So the answers are:
1. The fifth line has 5 marbles.
2. The seventh line has 3 marbles.
3. The eighth line has 2 marbles.

Imagine starting with nine marbles on the first line. As you follow the pattern, each line loses one marble, resembling a gentle slide down a fun slide! By the fifth line, hear the echoes of counting down: 9, 8, 7, 6, 5! So, you’ll find 5 marbles waiting for you there. Now, let's hop over to the seventh line! Following our mesmerizing slide down, you reach the countdown: 9, 8, 7, 6, 5, 4, 3! Woohoo! On the seventh line, you'll discover just 3 delightful marbles. And for the eighth line, give a quick count – that’s 9, 8, 7, 6, 5, 4, 3, 2! There you go, just 2 marbles rolling around there!
