The given sequence is defined as:

$a_n = 10(2)^n$

We are asked to find the first three terms of the sequence starting with $n = 1$.

Step-by-step calculation:

1. For $n = 1$: $a_1 = 10(2)^1 = 10 \times 2 = 20$

2. For $n = 2$: $a_2 = 10(2)^2 = 10 \times 4 = 40$

3. For $n = 3$: $a_3 = 10(2)^3 = 10 \times 8 = 80$

Final Answer:

The first three terms of the sequence are: $20, 40, 80$

1. What is the 5th term of this sequence?
2. How does the sequence grow as $n$ increases?
3. Can this sequence be classified as arithmetic or geometric?
4. What would happen to the sequence if the base were changed from 2 to another number?
5. How could you express the nth term using logarithms?

Tip: Always check the behavior of a sequence for small values of $n$ to understand its growth or pattern.
