The formula for the nth partial sum of a geometric series is S(n) = a1 (1 - r^n)/(1 - r) where a1 is the first term and r is the common ratio. In your case, a1 = 3, r = 5 and n = 5. Substituting, we get: S(5) = 3 (1 - 5^5)/(1 - 5) = 2343. Because the ratio has absolute value greater than 1, the series continues to grow as the index increases. Thus it is divergent.
