The correct option is C 21
Numbering the letters of the alphabet, we get:
A
B
C
D
E
F
G
H
I

19
20
21
22
23
24
25
26
Now, the letters on a computer keyboard begin as 'QWERTY'.
Writing down the number corresponding to each of these letters, we get:
Q
W
E
R
T
Y
17
23
5
18
20
25
This is the same as the given series: 17, 23, 5, 18, 20, 25
Hence, the next number in the series will be the number corresponding to the letter on the keyboard after 'Y'.
The letter after 'Y' on the keyboard = U
Number corresponding to 'U' = 21
Hence, the next number in the series will be 21.
Numbering the letters of the alphabet, we get:
| A | B | C | D | E | F | G | H | I | J | K | L | M |
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 |
| N | O | P | Q | R | S | T | U | V | W | X | Y | Z |
| 14 | 15 | 16 | 17 | 18 | 19 | 20 | 21 | 22 | 23 | 24 | 25 | 26 |
Now, the letters on a computer keyboard begin as 'QWERTY'.
Writing down the number corresponding to each of these letters, we get:
| Q | W | E | R | T | Y |
| 17 | 23 | 5 | 18 | 20 | 25 |
This is the same as the given series: 17, 23, 5, 18, 20, 25
Hence, the next number in the series will be the number corresponding to the letter on the keyboard after 'Y'.
The letter after 'Y' on the keyboard = U
Number corresponding to 'U' = 21
Hence, the next number in the series will be 21.
