Answer 1

To calculate how many people receive the email after each round of forwarding, we can set up the sequence based on the number of people each person forwards the email to.

In the first round, 10 people receive the email. In the second round, each of those 10 people forwards it to 10 more people, resulting in:

- Round 1: 10 people
- Round 2: 10 x 10 = 100 people
- Round 3: 100 x 10 = 1,000 people
- Round 4: 1,000 x 10 = 10,000 people
- Round 5: 10,000 x 10 = 100,000 people

So, the complete sequence for the total number of people receiving the email after each round is:

10, 100, 1,000, 10,000, 100,000.
