Answer:

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
