Interleaved arithmetic progressions (+11): find the missing term in the two intertwined sequences. Series given: 13, 32, 24, 43, 35, ?, 46, 65, 57, 76 Observe that odd and even positions each form an AP with common difference +11. Compute the missing value at the 6th position.

Q: Interleaved arithmetic progressions (+11): find the missing term in the two intertwined sequences. Series given: 13, 32, 24, 43, 35, ?, 46, 65, 57, 76 Observe that odd and even positions each form an AP with common difference +11. Compute the miss…

Split positions Odd positions: 13, 24, 35, 46, 57 → add 11 each time. Even positions: 32, 43, ?, 65, 76 → also add 11. Compute 32 → 43 (+11) → 54 (+11) → 65 (+11) → 76.

Difficulty: Easy

Correct Answer: 54

Explanation:

Split positions

Odd positions: 13, 24, 35, 46, 57 → add 11 each time.
Even positions: 32, 43, ?, 65, 76 → also add 11.

Compute
32 → 43 (+11) → 54 (+11) → 65 (+11) → 76.
