Answer 1

7

Explanation:

i did it on khan and i got it right

Answer 2

The 4th term is 7

Explanation:

we have

`C(n)=C(n-1)(1)/(2)`

`C(1)=56`

step 1

Find C(2)

For n=2

`C(2)=C(1)(1)/(2)`

`C(2)=(56)(1)/(2)=28`

step 2

Find C(3)

For n=3

`C(3)=C(2)(1)/(2)`

`C(3)=(28)(1)/(2)=14`

step 3

Find C(4)

For n=4

`C(4)=C(3)(1)/(2)`

`C(4)=(14)(1)/(2)=7`

therefore

The 4th term is 7
