               ### Assistant: We are given a geometric sequence with first term, a = 5/2 and common ratio, r = 1/2. We can find any term of the sequence using the formula a_n = a * r^(n-1). , The answer is The 20th term and nth term of the given G.P. are given by: 
a20 = ar19 = a * r^(20-1) = (5/2) * (1/2)^(20-1) 
an = ar(n-1) = a * r^(n-1) = (5/2) * (1/2)^(n-1)
