Find out the wrong number in the given sequence of numbers.19.8, 13, 21, 32, 47, 63, 8347633283
Question
Find out the wrong number in the given sequence of numbers.
19.8, 13, 21, 32, 47, 63, 8347633283
Solution
The sequence doesn't seem to follow a clear mathematical pattern at first glance. However, if we look closer, we can see that the difference between consecutive numbers is increasing by 2 each time:
- 13 - 19.8 = -6.8
- 21 - 13 = 8
- 32 - 21 = 11
- 47 - 32 = 15
- 63 - 47 = 16
The difference should have been 19 (15 + 4) instead of 16. Therefore, the number 63 is wrong. It should have been 66 (47 + 19) to follow the pattern.
The number 8347633283 is also wrong as it doesn't fit into this pattern at all.
