fifth term will be
ar⁴=2/27
while seventh term will be
ar^6=2/243
dividing them
r²=27/243
=> r=1/3
therefore
a=6
so third term will be
ar²
hence 6*1/9
2/3 is the answer
ar⁴=2/27
while seventh term will be
ar^6=2/243
dividing them
r²=27/243
=> r=1/3
therefore
a=6
so third term will be
ar²
hence 6*1/9
2/3 is the answer
