A) 0
B) 1
C) 2
D) \[-2\]
Correct Answer: A
Solution :
Sinceare in GP. Then, \[\log \,{{a}_{n}}\,=\log \,{{a}_{1}}\,+(n-1)\,\log \,r\] ?????? ?????? ?????? Now, Applying,and (since, two rows are identical) Alternate Solution Since,are in GP, then are in Ap. Given that where, a and c/ are the first term and common difference of an AP.
