To determine the value of a5, we can apply the given recursive formula an = an-1 - 5.
Given that a1 = 6, we can find the subsequent terms as follows:
a2 = a1 - 5 = 6 - 5 = 1
a3 = a2 - 5 = 1 - 5 = -4
a4 = a3 - 5 = -4 - 5 = -9
a5 = a4 - 5 = -9 - 5 = -14
Therefore, the value of a5 is -14.
if a1=6 and an=an-1-5 find the value of a5
