Given the recursive formula for the geometric sequence a1 = 5, a n = 2/5 a n-1, find the second term of the sequence.
A. a2 = 2/5
B. a2 = 5 2/5
C. a2 = 2
D. a2 = 8/5
To find the second term of the sequence, we need to substitute n = 2 into the recursive formula.
a2 = (2/5) * a1
a2 = (2/5) * 5
Simplifying, we get:
a2 = 2
Therefore, the second term of the sequence is 2.
The correct answer is C. a2 = 2.
