Answer: 80
Explanation The sequence 5, 10, 20, 40, 80, .... is an example of a geometric sequence . 5 + 5 = 10 10 + 10 = 20 20 + 20 = 40 40 + 40 = 80 The pattern is that we are always multiplying by a fixed number of 2 to the previous term to get to the next term.1

Answer: 16 36
Explanation 0, 44, 12, 40, 14, 38, ? Split into two separate sequences: First numbers (odd positions): 10, 12, 14 → increasing by 2 Second numbers (even positions): 44, 40, 38 → decreasing by 4, then 2 Let’s continue the same logic: - Next odd-position number: 14 + 2 = 16 - Next even-position number: 38 - 2 = 36
Answer: 2
Explanation 63, 48, 35, 15, ? Now, find the differences between consecutive terms: - 63 → 48 → −15 - 48 → 35 → −13 - 35 → 15 → −20 Wait, something's off. Let's double-check with consistent logic. Try this: 63 - 15 = 48 48 - 13 = 35 35 - 20 = 15 Now we got: -15, -13, -20 → Pattern doesn't seem linear. Try checking the alternating pattern: - 63 → 48 (−15) - 48 → 35 (−13) - 35 → 15 (−20) - 15 → ? (maybe −13 again?) If the pattern alternates between −15, −13, −20, −13, then: 15 − 13 = 2
Answer: 9/11
Explanation The given series is: 3/5, 5/7, 7/9, ? We can observe the pattern: - Numerators: 3, 5, 7, ... → increasing by 2 → next is 9 - Denominators: 5, 7, 9, ... → increasing by 2 → next is 11 Next term = 9/11
Answer: N
Explanation Find the 8th letter from A : A (1), B (2), C (3), D (4), E (5), F (6), G (7), H (8) Find the 7th letter from Z (counting backward) : Z (1), Y (2), X (3), W (4), V (5), U (6), T (7) Find the midway letter between H and T : The alphabetical sequence from H to T is: H, I, J, K, L, M, N, O, P, Q, R, S, T This range has 13 letters. The middle letter is the 7th letter in this sequence. Counting: H (1), I (2), J (3), K (4), L (5), M (6), N (7)
