Final answer:

The first five terms of the sequence are 1, 4, 9, 16, and 25 respectively. The sequence, defined by the nth term formula an = n2, does not converge as it diverges to infinity.

Step-by-step explanation:

The question involves a sequence where the nth term (an) is given by an expression that simplifies to n2. To find the first five terms of this sequence, we substitute the values of n starting with 1 and continue until we reach 5.

  1. For n=1: a1 = 12 = 1
  2. For n=2: a2 = 22 = 4
  3. For n=3: a3 = 32 = 9
  4. For n=4: a4 = 42 = 16
  5. For n=5: a5 = 52 = 25

To determine if the sequence converges, we look at the behavior of the terms as n approaches infinity. Since the terms n2 grow without bound, the sequence does not converge; instead, it diverges to infinity.
