Answer :
a(n) = a1 * r^(n-1)
a1 = first term = -8
r = common ratio = 5
a(2) = -8 * 5^(2-1)
a(2) = -8 * 5^1
a(2) = -40
a(3) = -8 * 5^(3 - 1)
a(3) = -8 * 5^2
a(3) = -8 * 25
a(3) = -200
a(4) = -8 * 5^(4 - 1)
a(4) = -8 * 5^3
a(4) = -8 * 125
a(4) = -1000
a(5) = -8 * 5^(5 - 1)
a(5) = -8 * 5^4
a(5) = -8 * 625
a(5) = -5000
a(6) = -8 * 5^(6-1)
a(6) = -8 * 5^5
a(6) = -8 * 3125
a(6) = -25,000
the first 6 terms are : -8, -40, -200, -1000, -5000, -25,000
a1 = first term = -8
