Answer:
9
Step-by-step explanation:
The ratio is 1/2 so the next term would always be half of the previous one.
- 72 times 1/2 is 36
-36 times 1/2 is 18
-18 times 1/2 is 9. So the answer is 9
Answer:
I think it's A. I may be wrong tho.
The answer is 35x-7.......
Answer:
she will need 8.4 so just get 9
T1 + d = 9/2
t5 = t1 + 4d = 6
Now we have two simultaneous equations:
t1 + 4d = 6 ............(1)
t1 + d = 9/2 ...........(2)
Subtracting (2) from (1) gives:
3d = 3/2
So the common difference d = 1/2
and by substitution in (1) we find t1 = 4
Therefore the 3rd term = 4 + (2 * 1/2) = 5
