Answer:
x = 1.02.
Step-by-step explanation:
The x is a factor worked out from  the annual interest  written as a decimal fraction.
So we have  2% = 2/100 = 0.02.
The amount at the end of the first year is $100 + 0.02*100 
= $100* 1.02,  and in  the second year it will be $100* 1.02^t  where t = 2 and so on.
So we see that x in the given expression is 1.02.
