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.
