THE THIRD TERM OF A G.P IS 2/3 & THE 6TH TRERM IS 2/81 FIND THE 8TH TERM
- 3rd term = ar2 = 2/3 _____________1
- 6th term = ar5 = 2/81 _____________2
- 2/1 = ar5/ar2 => r3 = 2/81*3/2 => r3 = 1/27 => r=1/3
- substituting it in 1 we get a = 6
- 8th term = ar7 =6*(1/3)7 = 6*1/2187 = 2/729 = ans
- hope u understood have a gud day :)
