Answer:

-3125

Explanation:

To find the value of a₆, we can use the given recursive formula and substitute the values for a₁ and the preceding terms until we reach the desired term.

Given:

a₁ = 1

aₙ = -5aₙ₋₁

Let's calculate the values step by step:

a₂ = -5a₁ = -5(1) = -5

a₃ = -5a₂ = -5(-5) = 25

a₄ = -5a₃ = -5(25) = -125

a₅ = -5a₄ = -5(-125) = 625

a₆ = -5a₅ = -5(625) = -3125

Therefore, the value of a₆ is -3125.

Hope this helps!
