D(1)=8
D(n)=d(n-1)•(-5)
Find the 3rd term

The 3rd term is 200

Step-by-step explanation:

∵ = 8

- That means the first term of the sequence is 8

∵ = . (-5)

- That means the next term is the product of the previous term and -5

∴ =  . (-5)

∵  = 8

∴ = 8 . (-5)

∴ = - 40  

∴ The 2nd term is -40

Let us find the third term

∵ =   . (-5)

∵ = - 40

∴ = (-40) . (-5)

∴   = 200

∴ The 3rd term is 200
