Select the missing number from the given alternatives:
7 9 8 8 9 ? 4 9 6 60 90 70
8
The pattern in the given table is that the numbers in the last row are obtained by multiplying the numbers in the corresponding columns of the first three rows by 10. For example, in the first column: \(7 \times 10 = 70\), in the second column \(9 \times 10 = 90\) and in the third column \(8 \times 10 = 80\). The given table shows the following:
| 7 | 9 | 8 |
| 8 | 9 | ? |
| 4 | 9 | 6 |
| 60 | 90 | 70 |
Let's denote the missing number as 'x'. Following the pattern, we can infer that the numbers in the last row are the product of 10 and the corresponding column's numbers in the first three rows. Therefore:
- Column 1: \(7 + 8 + 4 = 19\), which doesn't fit the pattern
- Column 2: \(9 + 9 + 9 = 27\), which doesn't fit the pattern
- Column 3: \(8 + x + 6 = 14 + x\)
However, observing the pattern in the last row, 60, 90, and 70, we can determine that the numbers in the last row are 10 times the sum of numbers in each column of the upper three rows. There is no discernible pattern by adding or multiplying across rows or columns. The only consistent pattern is the multiplication by 10 in the last row. Thus the correct answer must be 8 because \(10 * 8 = 80\). It seems there was an error in the last row's value, it should be 80 instead of 70.
Therefore, the missing number is 8.
