What is the total number of viruses one second before the amount reaches 655,360, assuming they quadruple every second?

409,600
163,840
655,360
1,310,720

The correct answer is: 163,840

To determine the total number of viruses one second before they reach 655,360, it's essential to understand the growth pattern indicated in the question. Given that the viruses quadruple every second, it means that the number of viruses is multiplied by four each second. If at a certain moment the number of viruses is 655,360, then one second prior, the count of viruses would be calculated by reversing the quadrupling effect. To find the count one second earlier, you would divide 655,360 by four. Calculating this yields: 655,360 ÷ 4 = 163,840. Therefore, one second before reaching 655,360, there are 163,840 viruses present. This is the correct answer, as it reflects the exponential growth pattern correctly applied in reverse to determine the previous count.
