What is the interest rate if a principal of $700 earns $196.00 in interest in seven years?

4%

Step-by-step explanation:

To solve this problem we can use a modified version of the simple interest formula which is shown below:

P = initial balance

I = interest

t = time

Plug the values into the equation:

The last step is to convert 0.04 into a percent:

0.04(100) = 4

The interest rate is 4%.

you need a common difference between consecutive terms to be constant, like 1,2,3,4 or 2,4,6,8, or 1,3,6,9

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
