Given parameters:
Principal = £1300
Interest rate = 5%
Duration = 2yrs
Unknown:
Total amount of Dan's principal = ?
To solve this problem, we apply the equation below:
Total investment worth = Principal + interest
Interest = 
where P is the principal
R is the rate
T is the time
Now, input the parameters;
Total investment worth = £1300 + £ 
= £1300 + £130
= £1430
The amount after two years is £1430
4+1 = 5
5 is the answer but you could also just subtract it a normal way

Let

denote the

th partial sum of the series, i.e.

Then

and subtracting from

we get


As

, the exponential term vanishes, leaving us with

and so
