How many such numbers are there in the above sequence, each of which is immediately preceded by a consonant and immediately followed by a symbol?
The answer is D: 3.
There are three numbers in the sequence that are immediately preceded by a consonant and immediately followed by a symbol. They are:
- 2 ($)
- 8 (%)
- 1 (@)
The other numbers in the sequence are either not preceded by a consonant or not followed by a symbol. For example, the number 6 is preceded by a symbol (@) but not followed by a consonant. The number 7 is preceded by a consonant (F) but not followed by a symbol.
The answer is B: @FN.
The series is created by alternating between two patterns:
- The first letter of each word is one letter earlier in the alphabet than the previous word.

Directions 26-30): Study the following arrangement and answer questions given:
A ^ D N 3 & G E 2 9 Q $ * C S 1 ) R I 4 M @ ! Z H 5 © K L U
Q. If all the symbols are dropped from the arrangement, then which of the following is the 8th letter to the right of the 18th letter from the right end?
The series becomes: A D N 3 G E 2 9 Q C S 1 R I 4 M Z H 5 K L U
Study the following arrangement and answer questions given:
A ^ D N 3 & G E 2 9 Q $ * C S 1 ) R I 4 M @ ! Z H 5 © K L U
Q. How many consonants are there in the arrangement each of which is immediately followed by a symbol?
Explanation:
Let's analyze the arrangement to identify consonants immediately followed by a symbol:
A ^ D N 3 & G E 2 9 Q $ * C S 1 ) R I 4 M @ ! Z H 5 © K L U
Here, we can see:
- Q $
- C *
- Z !
So, there are **three** consonants in the arrangement each of which is immediately followed by a symbol.
Answer: C: Two
Study the following arrangement and answer questions given:
A ^ D N 3 & G E 2 9 Q $ * C S 1 ) R I 4 M @ ! Z H 5 © K L U
Q. Complete the series: N&D E9G $CQ ?
Explanation:
To solve this problem, we need to identify a pattern or sequence in the given arrangement. The arrangement is:
A ^ D N 3 & G E 2 9 Q $ * C S 1 ) R I 4 M @ ! Z H 5 © K L U
Now, let's analyze the given series to be completed: N&D E9G $CQ
We can observe the following pattern:
- The first element of each group is a letter that appears in the original arrangement with a gap of 5 letters between them. For example, N (A ^ D N...), E (G E 2 9 Q...), and $ (* C S 1 ) R...).
- The second element is a symbol or number that appears exactly two steps after the first element in the original arrangement. For example, & (D N 3 &...), 9 (E 2 9 Q...), and C ($ * C S...).
- The third element is a letter that appears exactly three steps after the second element in the original arrangement. For example, D (N 3 & G E...), G (E 2 9 Q $...), and Q ($ * C S 1 ) R...).
Using this pattern, we can find the next group in the series:
- The first element should be a letter with a gap of 5 letters after Q in the original arrangement: R (1 ) R I 4...).
- The second element should be a symbol or number two steps after R in the original arrangement: 1 (R I 4 M @ ! Z H 5 © K L U).
- The third element should be a letter three steps after 1 in the original arrangement: S (1 ) R I 4 M @ ! Z H 5 © K L U).
So, the next group is 1RS. Therefore, the answer is:
D: 1RS
