Find the 8th term of the geometric sequence 5, -15, 45

FrozenT [24]

Answer:

a₈ = - 10935

Step-by-step explanation:

the nth term of a geometric sequence is

$a_{n}$ = a₁ $(r)^{n-1}$

where a₁ is the first term and r the common ratio

here a₁ = 5 and r = $\frac{a_{2} }{a_{1} }$ = $\frac{-15}{5}$ = - 3 , then

a₈ = 5 × $(-3)^{7}$ = 5 × - 2187 = - 10935

Complete the solution of the equation find the value of y when x equals 2. -8x - 5y = -1

tatuchka [14]

Answer: y = -3

Step-by-step explanation:

-8x - 5y = -1

+8x +8x

-5y = 8x - 1

÷-5 ÷-5 ÷-5

y = $-\frac{8}{5}x + \frac{1}{5}$

y(2) = $-\frac{8}{5}(2) + \frac{1}{5}$

= $-\frac{16}{5} + \frac{1}{5}$

= $-\frac{15}{5}$

= -3
