the last one
Step-by-step explanation:
Answer:
x = 8 is a solution for the equation
Answer: an = -3 · 2^n - 1
Step-by-step explanation:
In a geometric series, the consecutive terms differ by a common ratio. The formula for determining the nth term of a geometric progression is expressed as
an = a1 × r^(n - 1)
Where
a1 represents the first term of the sequence.
r represents the common ratio.
n represents the number of terms.
Looking at the given sequence,
a = - 3
r = - 6/ - 3 = 2
Therefore, the formula for the sequence is
an = - 3 × 2^(n - 1)
W,x,and y equal hte same so 4
