Correct Answer: 13, 10


Solution : Given:
22, 22, 23, 20, 16, 17, 17, ?, ?, 8

Odd position terms – The series follows a pattern of +1, –7, +1, –7, and so on.
22 + 1 = 23; 23 – 7 = 16; 16 + 1 = 17; 17 – 7 = 10
Even position terms – The series follows a pattern of –2, –3, –4, and so on.
22 – 2 = 20; 20 – 3 = 17; 17 – 4 = 13

So, the two missing terms are 13 and 10. Hence, the fourth option is correct.
