Question

What is the fifth term of the sequence whose first term is 10 and whose common ratio is 1/2 ?

Answer 1

\[10\times (\frac{1}{2})^4\]

Answer 2

or since \(2^4=16\) it is \(\frac{10}{16}\) maybe can reduce

Answer 3

I got 50

Answer 4

another way
first term is 10
second term is 5
third term is 2.5
fourth term is 1.25
fifth term is .625

Answer 5

oh no, it is not \(10\times 2^4\) it is \(\frac{10}{2^4}\)
