Given the recursive formula for the geometric sequence a1=5 , an=25an−1 , find the second term of the sequence.(1 point) Responses a2=2 a subscript 2 baseline equals 2 a2=25 a subscript 2 baseline equals Start Fraction 2 over 5 End Fraction a2=525 a subscript 2 baseline equals 5 Start Fraction 2 over 5 End Fraction a2=85
To find the second term of the geometric sequence, we can use the recursive formula.
Given: a1 = 5 and an = 25an-1
To find a2, we substitute n = 2 into the recursive formula:
a2 = 25a1 = 25(5) = 125
Therefore, the second term of the sequence is a2 = 125.
