Apparently, you're supposed to recognize that the formula tells you the value of cos(x/2).
A geometric series is the collection of an unlimited number of terms with a fixed ratio between them. The value of a₅ is -729.
<h3>What is geometrical series?</h3>A geometric series is the collection of an unlimited number of terms with a fixed ratio between them.
Given the value of a₁=9 and the value of . Therefore, the value of a₅ can be written as,
a₂ = -3(a₁) = -3(9) = -27
a₃ = -3(a₂) = -3(-27) = 81
a₄ = -3(a₃) = -3(81) = -243
a₅ = -3(a₄) = -3(-243) = -729
Hence, the value of a₅ is -729.
