Question -
Answer -
The nth term from theend is given by:
an = l(1/r)n-1 where, l is the last term, r is the common ratio, n isthe nth term
Given: last term, l =1/4374
r = t2/t1 =(1/6) / (1/2)
= 1/6 × 2/1
= 1/3
n = 4
So, an =l (1/r)n-1
a4 =1/4374 (1/(1/3))4-1
= 1/4374 (3/1)3
= 1/4374 × 33
= 1/4374 × 27
= 1/162
∴ 4th termfrom last is 1/162.
