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.
Each of the digits in the number 8642571 is arranged in ascending order from left to right. What will be the sum of the digits which are fourth from the left and second from the right in the new number thus formed?
