Answer: 1/8
Explanation Each term is half of the previous term: 2 → 1 (2 ÷ 2) 1 → 1/2 (1 ÷ 2) 1/2 → 1/4 (1/2 ÷ 2) So next term = 1/4 ÷ 2 = 1/8
Answer: 12
Explanation The given series is: 5, 7, 8, 10, 11, __, 13 Let’s look at the pattern: - 5 → +2 → 7 - 7 → +1 → 8 - 8 → +2 → 10 - 10 → +1 → 11 - 11 → +2 → 13 But 13 is at the end, so the missing number must be between 11 and 13. So we should insert +1 → 12 before +1 to get 13. Correct answer: A) 12 Pattern: +2, +1, +2, +1, +2, +1..
Answer: 86
Explanation The sequence appears to be formed by adding consecutive multiples of 4 : 1 + 1 = 2 2 + 4 = 6 6 + 16 = 22 22 + 64 = 86 So, the next number in the sequence would be 86 .
Answer: 13
Explanation HCF Stand for Highest Common factor The HCF of 26 and 91 is 13. Factor of 26 26 = 1 x 2 x 13 Factor of 91 91 = 1x 7 x 13 So highest is 13
Answer: 151
Explanation The sequence is formed by adding 10, then 20, then 40, and so on, increasing the increment by 10 each time: 1 + 10 = 11 11 + 20 = 31 31 + 40 = 71 71 + 80 = 151

Answer: 4
Explanation The prime numbers between 64 and 81 is = 67, 71 ,73,79
Answer: an = 5n − 7
Explanation an = 5n − 7 This is an arithmetic sequence with first term a = -2 and common difference d = 5. General formula: an = a + (n−1)d = -2 + (n−1)×5 = 5n − 7.
Answer: 9
Explanation In the question above, 3 × 2 + 2 = 8 6 × 2 + 2 = 14 Similarly, if we take '?' as 'a' a × 2 + 2 = 20 a × 2 = 18 a = 18/2 a = 9
Answer: 842
Explanation 3 + 5 = 8 3 + 4 = 7 2 + 4 = 6 1 + 8 = 9
