Answer:
-5
Step-by-step explanation:
Geometric sequences have common ratios.
You can see if a sequence is geometric by computing:
.
If you get the same result per consecutive pair, then there is a common ratio and the sequence is geometric.
Let's see:

So if this equations holds (if all 3 fractions equal the same thing), then is geometric and we have also have computed the common ratio.
The first fraction results in -250/50=-5.
The second fraction results in 50/-10=-5.
The third fraction results in -10/2=-5.
All three fractions are equal and so the equation holds so it is geometric and the common ratio is -5.
I think it is mk because 4 plus 2 is sixty
Answer:
y = 1
Step-by-step explanation:
6 = 2y + 4
6 - 4 = 2y
2 = 2y
y = 2/2
y = 1
Answer:
The selling price would be Rs 52.5
Step-by-step explanation:
Rs 50 is the actual cost and the 5% profit will amount to Rs 2.5 (50*5%) so total total sales price would be Rs 52.5( Rs 50 + Rs 2.5)
Another way to calculate is (Rs 50 * 1.05) = 52.5
