The following combinations are given based on the position of element in the above sequence. Which of them follow the same pattern ?
A. A K 4
B. Q A !
C. $\beta$ M T
D. # 4 P
E. 6 ! @
Choose the correct answer from the options given below :
The given sequence of characters is:
$S 7 @ P B 6 # ! 4 Q $ A T K $\beta$ 8 M$
The task is to identify which of the given combinations of three elements follows the same positional pattern derived from this sequence.
First, we assign a position index to each character in the sequence, starting from 1:
S(1), 7(2), @(3), P(4), B(5), 6(6), #(7), !(8), 4(9), Q(10), $(11), A(12), T(13), K(14), $\beta$(15), 8(16), M(17)
The pattern requires selecting three elements whose positions in the sequence, let's call them $p_1, p_2, p_3$. When these positions are sorted in ascending order ($p_{(1)} < p_{(2)} < p_{(3)}$), they must satisfy the following conditions:
We will now check each option against this identified pattern:
| Option | Elements | Positions in Sequence | Sorted Positions ($p_{(1)}, p_{(2)}, p_{(3)}$) | Position Differences ($p_{(2)}-p_{(1)}, p_{(3)}-p_{(2)}$) | Follows Pattern? |
| A | A K 4 | A(12), K(14), 4(9) | 9, 12, 14 | $12-9=3$, $14-12=2$ | Yes |
| B | Q A ! | Q(10), A(12), !(8) | 8, 10, 12 | $10-8=2$, $12-10=2$ | No |
| C | $\beta$ M T | $\beta$(15), M(17), T(13) | 13, 15, 17 | $15-13=2$, $17-15=2$ | No |
| D | # 4 P | #(7), 4(9), P(4) | 4, 7, 9 | $7-4=3$, $9-7=2$ | Yes |
| E | 6 ! @ | 6(6), !(8), @(3) | 3, 6, 8 | $6-3=3$, $8-6=2$ | Yes |
The combinations A, D, and E satisfy the positional pattern ($p_{(2)} - p_{(1)} = 3$ and $p_{(3)} - p_{(2)} = 2$). Therefore, these are the correct combinations.
