A
70
💡 Explanation:
This series follows an alternating pattern: +1, +5, with 70 as a reset anchor. The pattern is: 70, 71 (+1), 76 (+5), 70 (reset), 81 (+11 from previous reset), 86 (+5), 70 (reset), 91 (+21 from previous reset). The blank must be 70 to maintain this reset pattern every 4th position.
