Answer

The next line is \( 9 \times 48=432 \).

Solution

\( 9 \times 45=405 \) \( 9 \times 46=414 \) \( 9 \times 47=423 \) Notice that as the multiplier increases by 1, the product increases by 9. Therefore, the next multiplier is 48 and the product will be \( 9 \times 48=432 \). Thus, the next line is: \( 9 \times 48=432 \)

The Deep Dive

Looking at the pattern given, we can observe that each multiplication involves increasing the second number by 1 and the product increasing by 9 each time. So, the next line should be \( 9 \times 48=432 \). Thus, the complete line is \( 9 \times 48=432 \).
