Alphanumeric Series Pattern Analysis

The question asks to find the missing term in the alphanumeric series: 1Z, 3X, 5V, ?

We need to identify the pattern in both the numbers and the letters separately.

Number Pattern

  • The sequence of numbers is 1, 3, 5, ...
  • The difference between consecutive numbers is constant: $3 - 1 = 2$ and $5 - 3 = 2$.
  • This is an arithmetic progression with a common difference of 2.
  • The next number in the sequence is $5 + 2 = 7$.

Letter Pattern

  • The sequence of letters is Z, X, V, ...
  • These letters are part of the English alphabet in reverse order.
  • Let's look at their positions in the alphabet: Z (26), X (24), V (22).
  • The difference between the positions is decreasing: $26 - 24 = 2$ and $24 - 22 = 2$.
  • The pattern is subtracting 2 from the position of the previous letter.
  • The position of the next letter is $22 - 2 = 20$.
  • The 20th letter in the English alphabet is T.

Combined Term Determination

Combining the next number (7) and the next letter (T), the missing term is 7T.

Conclusion

The term that replaces the (?) in the alphanumeric series 1Z, 3X, 5V is 7T.
