Answer:

-3125

Explanation:

The simplest way to start with, is just to make a list.

a1 = 1

a2 = -5*a_(2 - 1)

a2 = -5*a_1

a2 = -5*1

a2 = -5

===========================

a3 = -5 * a2

a3 = -5*-5

a3 = 25

===========================

a4 = -5*a3

a4= -5*25

a4 = - 125

============================

a5 = -5 * a4

a5 = - 5 * - 125

a5 = -5 * -125

a5 = 625

======================

a6= -3125
