As it is clear by looking at the sequesnce that there is now change in numerator ..only denominator is decreasing with a common difference of 2 ..

So the 10th term can be imagined as  5/n
Where n is some number which we have to find out..

Since the denominator is generating a sequence  34 32 30 ..... which is in AP with common difference of -2
So n (which is 10th term) = a + 9 d ( a is first term and d is common difference)
Hence ... n = 34 -9(2)
hence n = 16

So the 10th term comes out to be = 5/16
