1 If 2 + 3 = 10, 7 + 2 = 63, and 6 + 5 = 66, then what is 8 + 4?
- 84
- 72
- 96
- 100
Correct!Wrong!Explanation
The pattern is a + b = a × (a + b). For 8 + 4: 8 × (8 + 4) = 8 × 12 = 96. -
-
2 If 5 + 3 = 28, 9 + 1 = 810, 8 + 6 = 214, and 5 + 4 = 19, then what is 7 + 3?
- 210
- 310
- 511
- 410
Correct!Wrong!Explanation
The pattern is a + b = (a − b) concatenated with (a + b). 7 − 3 = 4, 7 + 3 = 10 → 410. -
-
3 If 11 × 11 = 4, 22 × 22 = 16, and 33 × 33 = 36, then what is 44 × 44?
- 64
- 81
- 49
- 100
Correct!Wrong!Explanation
The pattern multiplies the sum of the digits: (1+1)×(1+1)=4, (2+2)×(2+2)=16, (3+3)×(3+3)=36. For 44: (4+4)×(4+4)=8×8=64. -
-
4 What comes next in the sequence: 3, 5, 9, 17, ?
- 31
- 35
- 37
- 33
Correct!Wrong!Explanation
Each term is double the previous term minus 1: 3×2−1=5, 5×2−1=9, 9×2−1=17, so 17×2−1=33. (Alternatively, add increasing powers of 2: +2, +4, +8, +16.) -
-
5 If 1 + 4 = 5, 2 + 5 = 12, and 3 + 6 = 21, then what is 8 + 11?
- 106
- 96
- 86
- 116
Correct!Wrong!Explanation
The pattern is a + b = a × (b + 1). For 8 + 11: 8 × (11 + 1) = 8 × 12 = 96. -
-
6 What comes next in the Fibonacci sequence: 0, 1, 1, 2, 3, 5, 8, ?
- 13
- 21
- 11
- 8
Correct!Wrong!Explanation
Each term is the sum of the two preceding ones. 5 + 8 = 13. -
-
7 What comes next: 2, 6, 12, 20, ?
- 28
- 32
- 30
- 34
Correct!Wrong!Explanation
Pattern is n × (n+1) where n starts at 1: 1×2=2, 2×3=6, 3×4=12, 4×5=20, then 5×6=30. -
-
8 If 1 = 1, 2 = 2, 3 = 6, 4 = 24, 5 = 120, then 6 = ?
- 600
- 720
- 120
- 840
Correct!Wrong!Explanation
The pattern is factorial: n! = n × (n-1) × … × 1. 6! = 6 × 5 × 4 × 3 × 2 × 1 = 720. -
-
9 If 12 = 6, 24 = 12, 36 = 18, then 48 = ?
- 18
- 30
- 36
- 24
Correct!Wrong!Explanation
Each result is half of the input: 12/2=6, 24/2=12, 36/2=18, so 48/2=24. -
-
10 If 2 = 6, 3 = 12, 4 = 20, 5 = 30, then 6 = ?
- 42
- 48
- 56
- 36
Correct!Wrong!Explanation
Pattern is n × (n+1): 2×3=6, 3×4=12, 4×5=20, 5×6=30, so 6×7=42. -
-
11 What comes next: 1, 4, 9, 16, 25, ?
- 64
- 49
- 36
- 25
Correct!Wrong!Explanation
These are perfect squares: 1²=1, 2²=4, 3²=9, 4²=16, 5²=25, so next is 6²=36. -
-
12 What comes next: 3, 7, 15, 31, ?
- 59
- 63
- 61
- 65
Correct!Wrong!Explanation
Each term is double the previous plus 1: 3×2+1=7, 7×2+1=15, 15×2+1=31, so 31×2+1=63. -
-
13 What comes next: 5, 7, 11, 17, 25, ?
- 39
- 33
- 37
- 35
Correct!Wrong!Explanation
Differences increase by 2 each time: +2, +4, +6, +8, then +10 gives 25+10=35. -
-
14 What comes next: 2, 8, 18, 32, ?
- 52
- 54
- 50
- 48
Correct!Wrong!Explanation
Pattern is 2 × n²: 2×1²=2, 2×2²=8, 2×3²=18, 2×4²=32, so 2×5²=50. -
-
15 What comes next: 0, 3, 8, 15, 24, ?
- 34
- 37
- 35
- 36
Correct!Wrong!Explanation
Pattern is n² − 1: 1²−1=0, 2²−1=3, 3²−1=8, 4²−1=15, 5²−1=24, so 6²−1=35. -
