Options:
A .  1575
B .  1825
C .  1525
D .  1875
Answer: Option D
:
D
The given sequence is 3, 15, 75, 375…
Let us divide each term in the above sequence by the term preceding it:
15÷3=5
75÷15=5
375÷75=5
We observe that each term in the sequece is 5 times the term preceding it.
So, the next term in the geometric sequence = 375×5=1875
