Question

7; 7(2)^n; initial number of people who receive the e - mail; the increasing factor; the number of people who receive the e - mail on day n, where n ≥ 2

Explanation:

Step1: Match initial value

The initial number of people is the starting count, which is 7.

Step2: Match growth factor

In the exponential form $7(2)^n$, the base 2 is the increasing factor.

Step3: Match day n count

The expression $7(2)^n$ calculates the number of people who receive the email on day $n$ (for $n\geq2$, as it models exponential growth from the initial 7).

Answer:

• $7$ → Initial number of people who receive the e-mail
• $2$ (from $7(2)^n$) → The increasing factor
• $7(2)^n$ → The number of people who receive the e-mail on day $n$, where $n \geq 2$
