How to find interval of convergence.

The formula for calculating the percent change in a value between two points in time is:

p

=

N

−

O

O

⋅

100

Where:

p

is the percent change - what we are solving for in this problem.

N

is the New Value - 5 in this problem.

O

is the Old Value - 4 in this problem.

Substituting and solving for

p

gives:

p

=

5

−

4

4

⋅

100

p

=

1

4

⋅

100

p

=

100

4

p

=

25

There was a 25% increase from 4 to 5.
