Given the recursive formula for the geometric sequence a1=5, an=25an−1, find the second term of the sequence.
To find the second term of the sequence, we can substitute n = 2 into the recursive formula.
a1 = 5 (given)
a2 = 25 * a1
Substituting n = 2, we get:
a2 = 25 * 5 = 125
Therefore, the second term of the sequence is 125.
