Question

Find the missing numbers in the following set

2	4	6	8	10
2	14	34	??	98

• A. 30
• B. 62
• C. 42
• D. 78

Answer 1

The Correct Option is B

The provided set consists of two rows. The first row is a sequence of even numbers: 2, 4, 6, 8, 10. The second row has numbers that do not follow the same progression: 2, 14, 34, ??, 98. To find the missing number, we must identify a pattern or rule connecting these numbers. By examining the pairs vertically, we notice a common approach is to investigate multiplicative or additive patterns, but in this case, consider the transformation from the upper number in the sequence.

Looking closely, each number in the second row can be derived by applying a mathematical operation on the number directly above it in the first row:

• For 2: From 2 in the first row, remains 2 in the second row.
• For 4: Multiplying 4 by 4 gives 16, but in the original sequence it should be close to 14; hence, maybe there's a subtraction for fine-tuning. 4*3 + 2 = 14.
• For 6: Similarly, 6*5 + 4 = 34.
• For 8: Applying the same operation: 8*x + y = ??. Let's determine x and y based on previous patterns, presuming each step increases progressively as in subtraction or addition. Aligning with reverse operations gives the relationship can be framed by applying the pattern increasing by 2 more than double of upper value then added successively as 2 above each previous. Thus 8*7+6=62 should hold meaningfully by this sequence obtained.

Therefore, following the consistent transformation identified and testing, the missing number is indeed 62.

Thus, the complete set would look like this based on the determined rule:

2	4	6	8	10
2	14	34	62	98
