Let's Solve the Mystery Number Puzzle! 🔢

Hey there, little math explorer! 🚀 Today we’re going on a number adventure to find a missing number in this sequence:

31 → 41 → ? → 61 → 71 → 81

Our mission: Figure out what number is hiding in the question mark spot! Let’s break it down step by step.

Step 1: Look for the Pattern 🔍

Patterns are like secret codes in numbers! Let’s see how the numbers change:

• Start at 31.
• Next is 41. Hmm, what’s the magic number we add to 31 to get 41? 41−31=1041−31=10
• Then comes the missing number. If the pattern is adding 10 each time, we do 41+10=5141+10=51.
• Check the next numbers: 51+10=6151+10=61, 61+10=7161+10=71, and so on! ✅

Step 2: Write the Answer 🎉

So the missing number is... \boxed{51}!

Fun Fact: When numbers go up by 10 each time, it’s like counting how many fingers you have in your hands! 🤚🖐️

Why Does This Work? 🤔

Imagine you’re jumping on a number line: every time you jump, you land 10 spaces ahead! 🌟

31 ➔ 41 ➔ 51 ➔ 61 ➔ 71 ➔ 81

Remember: Patterns are everywhere! Look for them in stairs, candy jars, or even the days of the week. Keep exploring! 🌈
