Yeah there is a way... Lemme give a typical question... Find the common difference of an arithmetic progression whose first term Is 1 and last term is 1023...
First term = T¹ =a Last term = Tn = a + (n-1)d
Since your given the values of the first and the last term... You can substitute
Tn = 1 + (1023-1)d
1023 = 1 + 1022d
1022d = 1023 - 1
1022d = 1022
common difference = 1...
So there is a way....
You can get the common difference using the two terms given...
To answer the question above we first need to know how much is the interest per year. In equation, 3% of $2500 is 75. 75 per year in 4 years is 300. So add $300 to the principal amount, the money after 4 years would be $2800.
