Answer:
C. 25
Step-by-step explanation:
The applicable rule of exponents is ...
a^b = 1/a^-b
Matching this pattern to your expression, you see that ...
a = 5
b = 2
Then ...
1/5^-2 = 5^2 = 25
This is a geometric sequence with a=2, r= -3/2.
Therefore,
a₁ = 2
a₂ = 2*(-3/2) = -3
a₃ = 2*(-3/2)² = 9/2 = 4.5
a₄ = 2(-3/2)³ = -27/4 = -6.75
a₅ = 2(-3/2)⁴ = 81/8 = 10.125
Answer:
In fractions, the first five terms are
2, -3, 9/2, -27/4, 81/8
In decimals, the first five terms are
2.000, -3.000, 4.500, -6.750, 10.125
