If r = -\sqrt{2}, and a5 = \sqrt{2}, what is the first term of the sequence?
shepuryov [24]

Answer: C

<u>Step-by-step explanation:</u>

Let x represent the first term (a₁)

a₁ = x

a₂ = x(-√2)  = -x√2

a₃ = -x√2(-√2)  = 2x

a₄ = 2x(-√2)   = -2x√2

a₅ = -2x√2(-√2)   = 4x

Since it is given the a₅ = √2, then we  can solve: 4x =√2

Divide both sides by 4 to get: x = \frac{\sqrt{2}}{4}

this can also be written as: \frac{1}{4}\sqrt{2}

Can anyone help me please?
vovangra [49]

Answer:

- 6

Step-by-step explanation:

The given statement implies that the slope of line formed by (5, r) is (3, -2) is -2, as they lie on the same line.

Slope(using these pts) = (y2 - y1)/(x2 - x1)

=> - 2 = (-2 - r)/(3 - 5)

=> -2 = (-2 - r)/(-2)

=> (-2)(-2) = (-2 - r)

=> 4 = -2 - r

=> r = - 2 - 4

=> r = - 6
