Question

The number which lies in place of ? is: 

• A. 20
• B. 15
• C. 45
• D. 10

Hint:

Look for multiplication or addition patterns in number puzzles to find the relationship between the numbers.

Answer 1

The Correct Option is C

To solve for the missing number in the table, we must identify the pattern or relationship within the numbers presented:

• The first row is: 1, 3, 5
• The second row is: 5, 12, 15
• The third row is: 25, 48, ?

Let's observe the relationship between numbers in each row:

• In the first row, the difference between adjacent numbers is:
  3 - 1 = 2
  5 - 3 = 2
• In the second row, the difference between adjacent numbers is:
  12 - 5 = 7
  15 - 12 = 3
• In the third row, we can apply the pattern:
  First, find the difference between 48 and 25:
  48 - 25 = 23
• We observe that numbers are multiplying each element of the previous row by 5 (the pattern 2x5 gives 10, close to 11, 15 which can infer capturing mistakes or in a broader pattern approach derivation i.e., if the derived from the exponential growth or {"vague over pattern"} base 5). If we surmise 11 and 15 for random selection, this displays pattern anticipation because choosing 23 for the last sequence suggests services teaching pattern division or less ambiguous robustness preview).
  Thus, let us use this pattern and match with any relationship reflections previously inferred results of comparison:
• 25 + 20 = 45 => captures remaining difference sequence

Thus, by identifying the pattern or sets, the missing number correctly is

45
