A = e; b = 2 f; n = 10.
The fourth term is:
T 4 = T (3+1) = ( 10 * 9 * 8 ) / ( 3 * 2 * 1 ) * e^7 * ( 2 f ) ^3 =
= 120 * e^7 * 2^3 * b^3 =
= 120 * 8 * e^7 * b^3 =
= 960 * e^7 * b^3

3/2 = 1.5
Let the value of the 1945 coin = x.
Then, the value of the 1950 coin = 1.5x
Together, they are worth $40. This gives us the equation:
x + 1.5x = 40
2.5x = 40
x = 40/2.5
x = 16
1.5x = 1.5 * 16 = 24
Answer: The 1945 coin is worth $16. The 1950 coin is worth $24.
