Question

Which term of the sequence is 7.5?

Answer 1

If this is the complete question with its accompanying choices:

Which term of the sequence is 7.5? 

n= 1, 2, 3, 4 
h(n)= 60, 30, 15, 7.5 

a) 1st 
b) 2nd 
c) 3rd 
d) 4th

Then 7.5 is the 4th term..

If n = 1, then h(n) = 60
If n = 2, then h(n) = 30
If n = 3, then h(n) = 15
If n = 4 ; then h(n) = 7.50

The succeeding number is equal to 1/2 of the preceding number.
