Which number breaks the Pattern ? 3, 6, 11, 20, 33, 70

Explanation:

Given series:
3, 6, 11, 20, 33, 70

📌 Check the pattern:

Let’s observe:

👉 Pattern:
Multiply by 2 and subtract increasing numbers

• $3 × 2 = 6$ ✔
• $6 × 2 − 1 = 11$ ✔
• $11 × 2 − 2 = 20$ ✔
• $20 × 2 − 3 = 37$ ❌ (but given is 33)

📌 Continue expected pattern:

• $20 × 2 − 3 = 37$
• $37 × 2 − 4 = 70$

👉 So correct sequence should be:
3, 6, 11, 20, 37, 70

❗ Error:

👉 33 is wrong (should be 37)

💡 Extra Tip:

In such series:

• Check multiplication + addition/subtraction pattern
• Look for increasing differences or constants

Final Answer:

33
