To find the first number in the 7496th row of a table where the numbers are arranged with six numbers per row, we can follow these steps:
-
Calculate how many numbers are in the first (n-1) rows: Each row has 6 numbers. Therefore, the total number of numbers in the first \( n \) rows is given by:
\[ \text{Total numbers} = 6 \times (n - 1) \]
For the 7496th row, the number of rows before it is \( 7495 \):
\[ \text{Total numbers in first 7495 rows} = 6 \times 7495 = 44970 \]
-
Determine the first number in the 7496th row: The first number in the 7496th row is one more than the total number of numbers in the first 7495 rows:
\[ \text{First number in the 7496th row} = 44970 + 1 = 44971 \]
Thus, the first number in the 7496th row is 44971.
