Question (English)

Which of the following numbers will replace the question mark (?) in the given series?
$1, 3, 10, 41, ?, 1237$

  1. 202
  2. 210
  3. 200
  4. 206 ✓ Correct
Explanation:

The series follows a pattern where each term is multiplied by consecutive integers starting from 2, and then 1 is added to the result.

Pattern: $\times n + 1$ (where $n = 2, 3, 4, 5, 6...$)

  • $1 \times 2 + 1 = 3$
  • $3 \times 3 + 1 = 10$
  • $10 \times 4 + 1 = 41$
  • $41 \times 5 + 1 = 205 + 1 = 206$
  • $206 \times 6 + 1 = 1236 + 1 = 1237$ (Check verified)

Therefore, the missing number is 206.

प्रश्न (हिंदी)

निम्नलिखित में से कौन सी संख्या दी गई श्रृंखला में प्रश्न चिह्न (?) का स्थान लेगी?
$1, 3, 10, 41, ?, 1237$

  1. 202
  2. 210
  3. 200
  4. 206
स्पष्टीकरण:

यह श्रृंखला एक पैटर्न का अनुसरण करती है जहाँ प्रत्येक पद को 2 से शुरू होने वाले क्रमागत पूर्णांकों से गुणा किया जाता है, और फिर परिणाम में 1 जोड़ा जाता है।

पैटर्न: $\times n + 1$ (जहाँ $n = 2, 3, 4, 5, 6...$)

  • $1 \times 2 + 1 = 3$
  • $3 \times 3 + 1 = 10$
  • $10 \times 4 + 1 = 41$
  • $41 \times 5 + 1 = 205 + 1 = 206$
  • $206 \times 6 + 1 = 1236 + 1 = 1237$ (जांच सत्यापित)

अतः, लुप्त संख्या 206 है।
