Final answer:
To find a specific number in a repeating pattern, divide by the pattern length and find the remainder. This remainder corresponds to the position in the pattern sequence. Therefore, without exact pattern details, we cannot conclude which statement is correct.
Step-by-step explanation:
The question deals with determining the 50th, 30th, and 40th numbers in a repeating pattern that repeats every 4 numbers. To figure out any specific number in the pattern, you would divide the position number by 4 and examine the remainder. The remainder after division will determine which number in the pattern it corresponds to.
For instance, if you were looking for the 50th number in the series, you would divide 50 by 4 which gives 12 with a remainder of 2. This means the 50th number would be the second number in the pattern. Similarly, dividing 30 by 4 gives 7 with a remainder of 2, indicating that the 30th number is also the second number in the pattern. For the 40th number, since 40 is a multiple of 4, it would be the last number in the pattern series. Without knowing the exact pattern, we cannot state definitively which number is in each position unless the repeating sequence is provided.
