Answer 1

The correct answer is option C

======================================
Explanation of the answer:

It is given that ⇒ a₁ = -6
So, we need to find which of the options will give us -6 by substituting with n=1

⇒ substitute with n = 1 in the equation of option A
∴
`a_(1) = -4*( (1)/(6) )^(n-1) = -4*( (1)/(6) )^(1-1)=-4*( (1)/(6) )^0 = -4`

⇒ substitute with n = 1 in the equation of option B

`a_(1) = (1)/(4) *(-6)^(n-1) = (1)/(4) *(-6)^(1-1) = (1)/(4) *(-6)^0 = (1)/(4)`

⇒ substitute with n = 1 in the equation of option C

∴
`a_(1) = -6*( (1)/(4) )^(n-1) = -6*( (1)/(4) )^(1-1)=-6*( (1)/(4) )^0 = -6`

⇒ substitute with n = 1 in the equation of option D


`a_(1) = (1)/(6) *(-4)^(n-1) = (1)/(6) *(-4)^(1-1) = (1)/(6) *(-4)^0 = (1)/(6)`
