Answer:
ii) AP
Step-by-step explanation:
a₁ , a₂ , a₃ in GP
=> a₂ / a₁ = a₃ / a₂ [ the common ratio ]
=> log ( a₂ / a₁ ) = log ( a₃ / a₂ )
=> log a₂ - log a₁ = log a₃ - log a₂ [ a common difference ]
=> log a₁ , log a₂ , log a₃ are in AP

=a1,a2,a3 in GP
=a1,a2,a3in GP [common ratio]
=log(a2/a1)=log (a3/a2)
log a2-log a1=log a3-log a2 (a common difference)
your answer is【AP】●●◆●◆◆
