8,000 / 1.9 = 4,200 500,000 / 1.9 = 263,157
Answer:
Option 1 is a geometric sequence.
I 1/4, 1/4, 1/4, 1/4
II 1/4, 1/5, 1/6
III 1/4, 1, -4, 1/6
IV 1/4, -4, 1/4, -4
For any geometric sequence there should be a common ratio
To find common ratio we divide consecutive terms
lets check option I
I 1/4, 1/4, 1/4, 1/4
When we divide 1/4 by 1/4 we will get 1
Same 1 for other two terms, so common ratio is 1
Hence the first option is a geometric sequence
