One day an e-mail is sent to 7 people. That day each person who receives the e-mail sends the email to two friends. Each friend who receives the email sends it to two more people on the following day

On the second day 28 people will have received the email.

To determine the expression that graphs this situation and determine the number of people who will have received the e-mail, the following calculation must be made:

Thus, if the email is forwarded two days in a row, this formula operates as follows:

Therefore, on the second day 28 people will have received the email.
