Term of rank n in a G.P: a₅ = arⁿ⁻¹
a₂ = a₁.r²⁻¹ = a₁.r = - 24
a₅ = a₁.r⁵⁻¹ = a₁.r₄ = 1536 ↔ a₁.r x r³ = 1536, but a₁.r = - 24
then: (-24) x r³ = 1536
r³ = (1536)/(-24) and r³ = - 64³ and r = ∛- 64 = r and r = -4
If r = -4 then a₁ =6 and the equation becomes :
a₅ =a₁r⁴ or a₅ =6(-4)⁴
Answer:
I think its 66 but i dont know. i took the test and had the same question but teachers are different

Hope this helps!!!:)
Step-by-step explanation:
I think it would be conditional, because B depends on A. Of A is false, then B isn’t possible, making it conditional.
