This question was previously asked in

The correct answer is
fg8hiij

To solve the problem, we need to identify the pattern in the given letter-number series and determine which letter-number combination fits into the blanks to complete the series. The series given is: \(d\_e\_f\_12g\_16h\_20i\_24\).

  1. The given characters are:
    • d
    • e
    • f
    • 12
    • g
    • 16
    • h
    • 20
    • i
    • 24
  2. Looking at the numbers:
    • 12, 16, 20, 24
    • 16 - 12 = 4
    • 20 - 16 = 4
    • 24 - 20 = 4
  3. Observing the existing letters:
    • d, e, f, g, h, i
  4. The pattern of the series can be identified as:
    • First part: d e f
    • Number: 12
    • Second part: g
    • Number: 16
    • Third part: h
    • Number: 20
    • Fourth part: i
    • Number: 24
  5. The missing parts between 'd' and 'e' should logically be 'f' and after 'f' should be 'g'. That makes the section 'd f e'. The number that immediately follows 'f e' (just before 12) logically fits the missing 8 based on the arithmetic sequence (12-4 = 8).
  6. The correct order to complete the sequence given the options is: fg8hiij.

Thus, the correct option is fg8hiij. Therefore, the complete sequence is: \(d\,f\,g\,8\,e\,f\,12\,g\,16\,h\,20\,i\,24\).
