Consider the sequence of numbers 3/8,3/4, 1 1/8,1 7/8 which statement is a description of the sequence?

The complete question in the attached figure

Let
for n=1
f(1)=3/8

for n=2
f(2)=3/4

for n=3
f(3)=1 1/8

for n=4
f(4)=1 1/2

for n=5
f(5)=1 7/8

we know that
f(2)-f(1)=3/4-3/8=3/8------> f(2)=f(1)+3/8

f(3)-f(2)=1 1/8-3/4----> 9/8-6/8----> 3/8-----> f(3)=f(2)+3/8

f(4)-f(3)=1 1/2-1 1/8-----> 12/8-9/8----> 3/8-----> f(4)=f(3)+3/8

f(5)-f(4)=1 7/8-1 1/2-----> 15/8-12/8---> 3/8-----> f(5)=f(4)+3/8

therefore

the answer is the option
The sequence is recursive and can be represented by the function f(n + 1) = f(n) + 3/8
