Answer:
The 4th term is 7
Step-by-step explanation:
we have
[tex]C(n)=C(n-1)\frac{1}{2}[/tex]
[tex]C(1)=56[/tex]
step 1
Find C(2)
For n=2
[tex]C(2)=C(1)\frac{1}{2}[/tex]
[tex]C(2)=(56)\frac{1}{2}=28[/tex]
step 2
Find C(3)
For n=3
[tex]C(3)=C(2)\frac{1}{2}[/tex]
[tex]C(3)=(28)\frac{1}{2}=14[/tex]
step 3
Find C(4)
For n=4
[tex]C(4)=C(3)\frac{1}{2}[/tex]
[tex]C(4)=(14)\frac{1}{2}=7[/tex]
therefore
The 4th term is 7
