Find the odd man out: 2, 6, 24, 120, 720, 5042
Answer:
5042
Step 1: Analyze the sequence: 2, 6, 24, 120, 720, 5042. Step 2: Identify that these are factorial numbers starting from 2! (2!, 3!, 4!, 5!, 6!). Step 3: The next expected factorial is 7! = 5040. Since 5042 is present, it is the odd man out.
2122
Which number does not belong to the group: 1, 2, 6, 24, 120, 722
Answer:
722
Step 1: Review the series: 1, 2, 6, 24, 120, 722. Step 2: The pattern follows the factorials of natural numbers: 1!, 2!, 3!=6, 4!=24, 5!=120. Step 3: The next factorial should be 6! = 720. The number 722 is the odd man out.
2123
Find the odd man out in the series: 2, 4, 6, 10, 16, 26, 44
Answer:
44
Step 1: Look at the numbers: 2, 4, 6, 10, 16, 26, 44. Step 2: Check for a Fibonacci-like pattern (2+4=6, 4+6=10, 6+10=16, 10+16=26). Step 3: The next term must be 16 + 26 = 42. Since 44 is given, it is the odd man out.
2124
Identify the odd one out: 4, 5, 9, 14, 23, 37, 61
Answer:
61
Step 1: Analyze the sequence: 4, 5, 9, 14, 23, 37, 61. Step 2: The pattern is based on adding the last two terms to obtain the next (4+5=9, 5+9=14, 9+14=23, 14+23=37). Step 3: The next value should be 23 + 37 = 60. The given value 61 is the odd man out.
2125
Find the odd man out: 5, 5, 10, 15, 25, 40, 66
Answer:
66
Step 1: Observe the given series: 5, 5, 10, 15, 25, 40, 66. Step 2: Understand the Fibonacci relationship. 5+5=10, 5+10=15, 10+15=25, 15+25=40. Step 3: The term after 40 should be 25 + 40 = 65. The number 66 is the odd man out.
2126
Which number is the odd man out: 1, 3, 4, 7, 11, 18, 30
Answer:
30
Step 1: Analyze the series: 1, 3, 4, 7, 11, 18, 30. Step 2: Identify the Lucas-style sequence where each term is the sum of the two preceding terms (1+3=4, 3+4=7, 4+7=11, 7+11=18). Step 3: The expected next term is 11 + 18 = 29. Therefore, 30 is the odd man out.
2127
Find the odd number in the series: 3, 4, 7, 11, 18, 29, 48
Answer:
48
Step 1: Examine the numbers: 3, 4, 7, 11, 18, 29, 48. Step 2: The pattern adds the previous two terms to get the next term (3+4=7, 4+7=11, 7+11=18, 11+18=29). Step 3: The next number should be 18 + 29 = 47. The given number 48 breaks the pattern.
2128
Identify the odd one out: 2, 3, 5, 8, 13, 21, 35
Answer:
35
Step 1: Look at the sequence: 2, 3, 5, 8, 13, 21, 35. Step 2: Recognize the Fibonacci-like pattern where the sum of the previous two numbers equals the next number (2+3=5, 3+5=8, 5+8=13, 8+13=21). Step 3: The term after 21 should be 13 + 21 = 34. The number 35 is the odd man out.
2129
Find the odd man out: 1, 1, 2, 3, 5, 8, 13, 22
Answer:
22
Step 1: Analyze the series: 1, 1, 2, 3, 5, 8, 13, 22. Step 2: This follows the Fibonacci sequence logic where each term is the sum of the two preceding terms (1+1=2, 1+2=3, 2+3=5, 3+5=8, 5+8=13). Step 3: The next term should be 8 + 13 = 21. Since 22 is given, it is the odd man out.
2130
Identify the odd one out in the series: 19, 28, 37, 46, 55, 64, 75
Answer:
75
Step 1: Examine the numbers: 19, 28, 37, 46, 55, 64, 75. Step 2: Check the sum of the digits for each number. The sum is 10 for all except the last one (1+9=10, 2+8=10, etc.). Step 3: For 75, the sum of digits is 7+5=12. Since it is not 10, 75 is the odd one out.
