Answer:a4=-42

Step-by-step explanation:

a1=0

an=2(a(n-1)-3)

a4=2(a(4-1)-3)

a4=2(a3-3)

a3=2(a(3-1)-3)

a3=2(a2-3)

a2=2(a(2-1)-3)

a2=2(a1-3) but a1=0

a2=2(0-3)

a2=2(-3)

a2=-6

a3=2(a2-3)

a3=2(-6-3)

a3=2(-9)

a3=-18

a4=2(a3-3)

a4=2(-18-3)

a4=2(-21)

a4=-42

What is the explicit rule for this sequence?<br> -5, 15, – 45, 135, ...
hoa [83]

Answer:

Step-by-step explanation:

In a geometric sequence, consecutive terms differ by a common ratio. The formula for determining the nth term of a geometric progression is expressed as

an = a1r^(n - 1)

Where

a represents the first term of the sequence.

r represents the common ratio.

n represents the number of terms.

From the given sequence,

a1 = - 5

r = 15/- 5 = - 3

Therefore, the explicit rule for this sequence is

an = - 5(- 3)^n - 1

Find thetwo consecutive integers whose product is 24​
malfutka [58]

Answer:

There is no solution to this equation that is an integer for x.

Step-by-step explanation:

x is the first integer, and x+1 the second

x(x+1) = 24\\x^{2} + x - 24 =0\\

x = \frac{-1+\sqrt{1^{2}+4*24}}{2} =\frac{-1+\sqrt{97}}{2}\\x = \frac{-1-\sqrt{1^{2}+4*24}}{2} =\frac{-1-\sqrt{97}}{2}
