, an=25an−1
, find the second term of the sequence.(1 point)
Responses

a2=5 2/5
a subscript 2 baseline equals 5 Start Fraction 2 over 5 End Fraction

a2=2
a subscript 2 baseline equals 2

a2=85
a subscript 2 baseline equals Start Fraction 8 over 5 End Fraction

a2=25

Answer 1

a2 = (2/5)·5 = 2.

(So the correct choice is a2 = 2.)
