Question

What is the 4th term in the sequence? C(1)=56 C(n)= c(n-1)•1/2

Answer 1

Answer:

The 4th term is 7

Step-by-step explanation:

we have

$C(n)=C(n-1)\frac{1}{2}$

$C(1)=56$

step 1

Find C(2)

For n=2

$C(2)=C(1)\frac{1}{2}$

$C(2)=(56)\frac{1}{2}=28$

step 2

Find C(3)

For n=3

$C(3)=C(2)\frac{1}{2}$

$C(3)=(28)\frac{1}{2}=14$

step 3

Find C(4)

For n=4

$C(4)=C(3)\frac{1}{2}$

$C(4)=(14)\frac{1}{2}=7$

therefore

The 4th term is 7
