A series of English number related words is given as Double, Triple, Quadruple, ?. Choose from the options the correct next term that continues this numerical word pattern.

Introduction / Context:
This is a simple verbal series question based on English words that describe multiplication factors or counts. The sequence Double, Triple, Quadruple refers to two times, three times, and four times respectively. You must identify the next standard English word in this increasing pattern.

Given Data / Assumptions:

• Given series: Double, Triple, Quadruple, ?
• Options: Quintuple, Nonuple, Sextuple, Octuple, Decuple.
• Each word corresponds to a specific integer multiple.

Concept / Approach:
These words come from Latin based numerical prefixes:

• Double corresponds to 2.
• Triple corresponds to 3.
• Quadruple corresponds to 4.
• Quintuple corresponds to 5.
• Sextuple corresponds to 6.
• Octuple corresponds to 8.
• Nonuple corresponds to 9.
• Decuple corresponds to 10.

The series is clearly increasing by one in the underlying numerical value, so we need the word that represents 5.

Step-by-Step Solution:
Step 1: Map each given word to its numeric meaning: Double = 2, Triple = 3, Quadruple = 4. Step 2: Recognise that the pattern is 2, 3, 4, and logically continues to 5. Step 3: Identify from the options which word stands for 5. Quintuple is formed from the root quinque or quint, which refers to five. Step 4: Verify other options. Sextuple is related to six, Nonuple to nine, Octuple to eight, and Decuple to ten. These do not fit directly after four. Step 5: Therefore, the word that continues the numerical word pattern after Quadruple is Quintuple, representing five times.

Verification / Alternative check:
Often, these words appear in mathematical puzzles and combinatorics descriptions. You can recall a simple increasing list Double (2), Triple (3), Quadruple (4), Quintuple (5), Sextuple (6), Septuple (7), Octuple (8), Nonuple (9), Decuple (10). The presence of the prefix quint as five confirms that Quintuple is the next term after Quadruple.

Why Other Options Are Wrong:
Nonuple corresponds to nine times, which would be much further along the sequence. Sextuple corresponds to six times, which would logically come after Quintuple, not immediately after Quadruple. Octuple represents eight times, again much later in the sequence. Decuple corresponds to ten times, which is also far beyond the immediate next step of five.

Common Pitfalls:
Some candidates may not be familiar with the meanings of words like Nonuple or Decuple and may guess based solely on sound. Others may confuse Quintuples position with some other Latin derived term. Memorising or at least recognising the core Latin roots for small numbers helps avoid such mistakes.

Final Answer:
The correct next term in the series Double, Triple, Quadruple is Quintuple, which denotes five times.
