Question

What is the 1oth term of this sequence
0.75,1.5,3,6,12

Answer 1

If you mean 10th, the answer would go:
.75,1.5,3,6,12,24,48,96,192,384.
So, final answer is 384

Answer 2

seems to be a geometric sequence which is found by

`a_(n)=a_(1)(r)^(n-1)`

an=nth term
a1=first term
r=common ratio

first term is 0.75
it doubles each time so common ratio is 2


`a_(n)=0.75(2)^(n-1)`
to find the nth term, input n and evaluate
example
to find the 20th term

`a_(50)=0.75(2)^(20-1)`

`a_(50)=0.75(2)^(19)`

`a_(50)=0.75(1048576)`

`a_(50)=786432`


just to find the kth term, input k for n in

`a_(n)=a_(1)(r)^(n-1)`
