Find the odd man out: 7, 14, 10, 20, 16, 32, 27
Answer:
27
Step 1: Analyze the sequence: 7, 14, 10, 20, 16, 32, 27. Step 2: Check the alternating pattern: *2, -4. (7*2=14, 14-4=10, 10*2=20, 20-4=16, 16*2=32). Step 3: The next step is -4. 32 - 4 = 28. The number 27 breaks the pattern.
2142
Which number does not belong to the group: 1, 4, 3, 12, 11, 44, 42
Answer:
42
Step 1: Review the series: 1, 4, 3, 12, 11, 44, 42. Step 2: Discover the rule alternating *4 and -1. (1*4=4, 4-1=3, 3*4=12, 12-1=11, 11*4=44). Step 3: The next operation is -1. 44 - 1 = 43. Since 42 is present, it is the odd man out.
2143
Find the odd man out in the series: 100, 50, 52, 26, 28, 14, 18
Answer:
18
Step 1: Look at the numbers: 100, 50, 52, 26, 28, 14, 18. Step 2: The pattern alternates with /2 and +2. (100/2=50, 50+2=52, 52/2=26, 26+2=28, 28/2=14). Step 3: The next step is +2. 14 + 2 = 16. The number 18 is given, making it the odd man out.
2144
Identify the odd one out: 2, 5, 4, 7, 6, 9, 7
Answer:
7
Step 1: Analyze the sequence: 2, 5, 4, 7, 6, 9, 7. Step 2: The pattern alternates between +3 and -1. (2+3=5, 5-1=4, 4+3=7, 7-1=6, 6+3=9). Step 3: The next operation is -1. 9 - 1 = 8. The last number is 7, which breaks the pattern.
2145
Find the odd man out: 3, 6, 5, 10, 9, 18, 16
Answer:
16
Step 1: Observe the given series: 3, 6, 5, 10, 9, 18, 16. Step 2: Note the operations between terms: *2, -1. (3*2=6, 6-1=5, 5*2=10, 10-1=9, 9*2=18). Step 3: The next operation should be -1. 18 - 1 = 17. Since 16 is given, it is the odd man out.
2146
Which number is the odd man out: 20, 10, 12, 6, 8, 4, 5
Answer:
5
Step 1: Analyze the series: 20, 10, 12, 6, 8, 4, 5. Step 2: Find the alternating operations: /2, +2. (20/2=10, 10+2=12, 12/2=6, 6+2=8, 8/2=4). Step 3: The next operation is +2. 4 + 2 = 6. The number 5 is given, making it the odd man out.
2147
Find the odd number in the series: 1, 2, 4, 5, 10, 11, 24
Answer:
24
Step 1: Examine the numbers: 1, 2, 4, 5, 10, 11, 24. Step 2: Discover the alternating rule: +1, *2. (1+1=2, 2*2=4, 4+1=5, 5*2=10, 10+1=11). Step 3: The next expected operation is *2. 11 * 2 = 22. The number 24 breaks the pattern.
2148
Identify the odd one out: 5, 10, 8, 16, 14, 28, 25
Answer:
25
Step 1: Look at the sequence: 5, 10, 8, 16, 14, 28, 25. Step 2: Check the alternating pattern: *2, -2. (5*2=10, 10-2=8, 8*2=16, 16-2=14, 14*2=28). Step 3: The next operation should be -2. 28 - 2 = 26. Since 25 is present, it is the odd man out.
2149
Find the odd man out: 10, 12, 11, 13, 12, 15, 13
Answer:
15
Step 1: Analyze the alternating series: 10, 12, 11, 13, 12, 15, 13. Step 2: Determine the operations. The pattern is +2, -1, +2, -1. (10+2=12, 12-1=11, 11+2=13, 13-1=12). Step 3: The next operation should be +2. Thus, 12 + 2 = 14. Since 15 is given, it is the odd man out.
2150
