Initally 3 people have a bacterial infection. The next day, everyone infected person infects one more person. If this pattern contiues , how many days will it take for 24 people to be infected?

To determine the number of days it will take for 24 people to be infected, we can analyze the pattern:

Day 1: 3 people infected
Day 2: 3 x 1 = 3 people infecting one more each = 6 people infected
Day 3: 6 x 1 = 6 people infecting one more each = 12 people infected
Day 4: 12 x 1 = 12 people infecting one more each = 24 people infected

Based on the pattern, it will take 4 days for 24 people to be infected.
