What should come in place of the question mark (?) in the given series- 90 90 91 95 104 ?

📘 Step-by-step Solution (व्याख्या)

Series:
90, 90, 91, 95, 104, ?

🔍 Difference निकालते हैं:

• 90 → 90 = 0
• 90 → 91 = +1
• 91 → 95 = +4
• 95 → 104 = +9

🧠 Pattern समझें:

Differences हैं:
👉 0, 1, 4, 9

यह हैं:
👉 0², 1², 2², 3²

➡️ Next difference:

👉 4² = 16

➡️ Final calculation:

104 + 16 = 120

🎯 Final Answer: 120

📚 हिन्दी में समझें

अंतर (difference) है:
👉 0, 1, 4, 9 = (0², 1², 2², 3²)

अगला अंतर:
👉 4² = 16

👉 104 + 16 = 120
