Final answer:

The sum of two convergent sequences is also a convergent sequence, where the limit of the sum is equal to the sum of the individual limits of the sequences.

Step-by-step explanation:

If an and bn are convergent sequences, we can deduce that the limit of the sequence formed by the sum of these two, an + bn, is also convergent. According to the properties of limits, specifically the sum rule for limits, if the limit of an as n approaches infinity is L and the limit of bn as n approaches infinity is M, then the limit of the sum is L + M.

In other words, if:

  • lim an = L
  • lim bn = M

Then:

  • lim (an + bn) = lim an + lim bn = L + M

This outcome is guaranteed by the limit laws that state the limit of a sum is equal to the sum of the limits, provided that the limits exist and are finite.
