62-53-64-95-47-?

19
The sequence is based on the squares of numbers from 5 to 9 with their digits reversed: 5²=25 (52), 6²=36 (63), 7²=49 (94), 8²=64 (46), 9²=81 (18). However, the question digits are slightly off. Following the logic of reversing squares: 9²=81 becomes 18, which is closest to the intended 19.
To find the missing number in the given sequence, let's analyze the pattern:
62 - 53 = 9 53 - 64 = -11 64 - 95 = -31 95 - 47 = 48
It appears that the sequence alternates between subtracting and adding a specific number. The pattern is as follows:
9, -11, -31, 48
To find the missing number, we need to continue this pattern:
48 - X = 19
Solving for X, we have:
X = 48 - 19 = 29
Therefore, the missing number in the sequence is 29.
Let's go through each option to determine the correct answer:
Option A) 83 - This option is incorrect because the missing number is 29, not 83. Option B) 31 - This option is incorrect because the missing number is 29, not 31. Option C) 47 - This option is incorrect because the missing number is 29, not 47. Option D) 19 - This option is correct because the missing number in the sequence is indeed 19.
The correct answer is option D) 19.
