hi
so the amount will be increased by 1 + 3/100 = 1.03

The sum of an Arithmetic Series is given as:

where,
d = Common Difference = Difference of any two consecutive terms.
So,
d = 8
a1 = First term = 1
Using the values, we get:

The above equation gives the formula for n terms of an Arithmetic Series.
So, option A is the correct answer
Move the decimal to the left where 70% becomes (.70). Then divide 14/.70 which equals 20.
