Question

Find the first four terms of the sequence represented by the expression 8(1/2)n

Answer 1

\(8\times \left(\frac{1}{2}\right)^n\)

Answer 2

replace \(n\) by 1 get \(8\times \left(\frac{1}{2}\right)^1=8\times \frac{1}{2}=4\)

Answer 3

now for the next one, you can replace \(n\) by 2, or more simply take half of 4
third one is half of 2 etc
