Final answer:
The correct sequence of numbers that consists of only the digit four is D) 4, 44, 444, 4444. This sequence exclusively contains the digit four in increasing quantities, with no other digits.
Step-by-step explanation:
The student is asking for a sequence of numbers that consists of the digit four and only fours. Looking at the given options:
- A) 4, 14, 24, 34
- B) 40, 41, 42, 43
- C) 14, 24, 34, 44
- D) 4, 44, 444, 4444
The correct answer is D) 4, 44, 444, 4444. This sequence matches the criteria because each number is composed entirely of the digit four. We can see that each number in this sequence progressively has more fours, without any other digit being involved.
