Number of letters skipped in between the adjacent letters in the series decreases by two. Which of the following series observes this rule?
a) FQWBG
b) HQXCF
c) TBINO
d) XFMQU
Answers
Answer:
(c) HQXCF
Explanation:
Let us look at each option.
To solve this, the best method is to convert the alphabets to their corresponding number, instead of doing it one by one.
OPTION A: FQWBG --> 6 17 23 2 7
The difference between 6 and 17 is 11, then the next difference should be 9, but it is 6, so this option does not observe this rule.
OPTION B: HQXCF --> 8 17 24 3 6
The Difference between 8 and 17 is 9
Between 17 and 24 is 7
Between 24 and 3 (26+3 = 29) is 5
Between 3 and 6 is 3
All are decreasing by 2. Precisely why this was right.
OPTION C: TBINO --> 20 2 9 14 15
Between 20 and 2 (26 + 2 = 28) is 8
Between 2 and 9 is 7
It has been violated, so no.
OPTION D: XFMQU --> 24 6 13 17 21
Between 24 and 6 (26 + 6 = 32) is 8
Between 6 and 13 is 7
It has been violated, so no.
Hope it Helps,
