Answer 1

Answer:

On the 6th mailing there are 4096 letters

Step-by-step explanation:

A geometric sequence is given by

an = a1 *r^(n-1)

Where a1 is the first term and r is the common ratio (what we multiply by each time) and n is the term number

The first person has mails 4 letters  so a1 =4

Each person sends 4 so the common ratio is 4

We are finding the 6th mailing

a6 = 4 (4) ^ (6-1)

a6 = 4*4^5

a6 = 4096
