Find the odd man out: 7, 14, 28, 56, 112, 220
Answer:
220
Step 1: Analyze the sequence: 7, 14, 28, 56, 112, 220. Step 2: Determine that the pattern is a geometric progression with a ratio of 2 (x2). Step 3: The next term should be 112 x 2 = 224. The number 220 breaks this pattern.
2172
Which number does not belong to the group: 1, 5, 25, 125, 625, 3120
Answer:
3120
Step 1: Review the series: 1, 5, 25, 125, 625, 3120. Step 2: Each number is derived by multiplying the previous number by 5 (x5). Step 3: The expected next number is 625 x 5 = 3125. The number 3120 is the odd man out.
2173
Find the odd man out in the series: 10, 20, 40, 80, 160, 320, 650
Answer:
650
Step 1: Look at the numbers: 10, 20, 40, 80, 160, 320, 650. Step 2: Recognize the pattern of doubling each term (x2). Step 3: The next term after 320 should be 320 x 2 = 640. Since 650 is in its place, 650 is the odd man out.
2174
Identify the odd one out: 4, 12, 36, 108, 324, 970
Answer:
970
Step 1: Analyze the sequence: 4, 12, 36, 108, 324, 970. Step 2: Notice the constant multiplier of 3 (x3) for each term. Step 3: The value after 324 should be 324 x 3 = 972. The number 970 does not fit and is the odd man out.
2175
Find the odd man out: 2, 6, 18, 54, 162, 480
Answer:
480
Step 1: Observe the given series: 2, 6, 18, 54, 162, 480. Step 2: Identify the pattern as multiplying the previous term by 3 (2x3=6, 6x3=18, etc.). Step 3: The expected next term is 162 x 3 = 486. The given number 480 is the odd man out.
2176
Which number is the odd man out: 1, 3, 9, 27, 81, 243, 720
Answer:
720
Step 1: Analyze the series: 1, 3, 9, 27, 81, 243, 720. Step 2: The pattern is a geometric sequence where each number is multiplied by 3. Step 3: The next term should be 243 x 3 = 729. Because 720 is given, it is the odd man out.
2177
Find the odd number in the series: 5, 10, 20, 40, 80, 150, 320
Answer:
150
Step 1: Examine the numbers: 5, 10, 20, 40, 80, 150, 320. Step 2: Check the multiplication pattern. Each term is multiplied by 2. Step 3: The term after 80 should be 80 x 2 = 160. The number 150 breaks this rule, so it is the odd man out.
2178
Identify the odd one out: 3, 9, 27, 81, 243, 730
Answer:
730
Step 1: Look at the sequence: 3, 9, 27, 81, 243, 730. Step 2: The pattern is a multiplication by 3 (x3) for each subsequent term. Step 3: Following 243, the next term should be 243 x 3 = 729. Since 730 is given, it is the odd man out.
2179
Find the odd man out: 2, 4, 8, 16, 32, 64, 120
Answer:
120
Step 1: Analyze the series: 2, 4, 8, 16, 32, 64, 120. Step 2: Observe the geometric progression where each term is multiplied by 2 (x2). Step 3: The term after 64 should be 64 x 2 = 128. Therefore, 120 is the odd man out.
2180
Identify the odd one out in the series: 3, 7, 11, 15, 19, 24, 27
Answer:
24
Step 1: Examine the numbers: 3, 7, 11, 15, 19, 24, 27. Step 2: Notice the arithmetic progression where the common difference is +4. Step 3: The number after 19 should be 19 + 4 = 23. Instead, 24 is given, making it the odd one out.
