Answer:
The first increase was of 60%.
Step-by-step explanation:
The initial value of the product is x.
The first increase was of y.
The second increase is of 25%, that is, 1.25.
The final price was double the original, so 2x.
This situation can be modeled by the following equation:

We want to find y.
Simplifying by x



After the first increase, the value was 1.6 of the original value, that is a increase as a percent of (1.6 - 1)*100 = 60%.

Answer:

Step-by-step explanation:
The terms of the sequence are:

We can rewrite the terms in factored form to get;

We can see that the subsequent terms are obtained by multiplying the previous term by
. This is called the common ratio.
Therefore the first term of this geometric sequence is
and the common ratio is
.
The nth term of a geometric sequence is given by:
.
Let us substitute the first term, the common ratio, and
to obtain:
