In a geometric sequence {an}, if a1 = 6 and r = 1.2, find a38. a) 273.6 b) 326.26 c) 5103.3735 d) 6124.0482

To calculate for the nth term of a geometric sequence, we use the formula,
                                      an = a1(r)^(n - 1)
where an is the nth term, a1 is the first term, r is the common ratio, and n is the number of terms. Substituting the known values,
                                      an = (6)(1.2)^(38 - 1) = 5103.37
Thus, the answer to this item is letter C.
