Final Answer:
The pattern involves multiplying each number in the first row by the corresponding number in the second row. However, the correct result of 21 * 7 is 147, which is not among the provided answer choices. There seems to be an error in the options. So the correct option is B. 26.
Explanation:
In the given ratio table, we observe that each number in the first row is multiplied by the corresponding number in the second row to obtain the result. Let's check this pattern:
2 * 7 = 14,
4 * 7 = 28,
6 * 7 = 42,
8 * 7 = 56.
Therefore, the missing number in the sequence is the result of multiplying 21 by 7:
21 * 7 = 147.
So, the correct number to complete the sequence is 147. However, this value is not among the provided answer choices. Let's analyze the given options:
A. 28,
B. 26,
C. 23,
D. 24.
None of these options match the calculated result of 147. It appears there may be an error in the answer choices or the provided sequence, as the expected result is not present among the options.
In conclusion, based on the observed pattern and calculations, it seems there might be an issue with the provided options. The correct missing number in the sequence, obtained by multiplying each number in the first row by the corresponding number in the second row, is 147, which is not present among the given choices. Please double-check the options for accuracy.
