What Are Decimal Sequences?
Decimal sequences are lists of numbers with decimal points that follow a special pattern or rule.
Just like whole number sequences, decimal sequences can increase or decrease by a fixed amount, or follow more complex patterns. Understanding these patterns helps us predict what comes next!
How to Find the Pattern
1️⃣ Look at the difference between consecutive numbers
2️⃣ Check if the numbers are being multiplied or divided
3️⃣ Test your pattern by applying it to the next number
Let's Practice Together!
Example 1: Adding Sequence
Find the next number in this sequence: 2.5, 3.0, 3.5, 4.0, _____
The pattern is: each time
So the next number should be:
Example 2: Multiplying Sequence
Find the next number in this sequence: 0.8, 1.6, 3.2, 6.4, _____
The pattern is: × each time
So the next number should be:
Parent Tips 🌟
- Use money - Practice with dollar amounts ($1.25, $1.50, $1.75) to make it practical
- Create sequence challenges - Take turns making sequences for each other to solve
- Connect to measurements - Use rulers or measuring cups to show decimal sequences in real life
