Question

Given the explicit rule, f(n) = 3・2n, generate the first four terms in the sequence.

Answer 1

• as written: 6, 12, 18, 24
• perhaps: 6, 12, 24, 48

Explanation:

The rule shown simplifies to ...

f(n) = 6n

So, the first four terms are ...

6{1, 2, 3, 4} =

6, 12, 18, 24

__

Perhaps you intend ...

f(n) = 3·2^n

For this, the first 4 terms are ...

3{2, 4, 8, 16} =

6, 12, 24, 48
