Geometric series like this are defined by a start term and a common ratio. The start term here is 6462, the common ration is 1.08.
The nth term of a progression is given by arⁿ⁻¹ where a is the start term and r is the ratio.
2001 = 6462
2002 = 6462 * 1.08 = 6979
2003 = 6979 * 1.08 = 7537
2004 = 7537 * 1.08 = 8140
B) nth term = 6462 * 1.08ⁿ⁻¹
C) n = 20. 6462 * 1.08^19 = 27888
