4 less than half a number is equal to 2 more than the number
xxMikexx [17]

Answer:

-12

Step-by-step explanation:

Let that number be x. We can build an equation, and solve for x.

4 less than half of x is x/2-4.

2 more than x is x+2.

We are given that the two quantities are equal, so we have that x/2-4=x+2.

Adding 4 to both sides gives x/2=x+6.

Multiplying both sides by 2 gives x=2(x+6)=2x+12.

Subtracting 2x from both sides gives -x=12.

Multiplying both sides by -1 gives x=-12.

So, the number is \boxed{-12} and we're done!

The check is left as an exercise to the reader.

Two terms of a geometric sequence are given. Find the first five terms. Please help asap
Zepler [3.9K]

Answer:

4, 8, 16, 32, 64

Step-by-step explanation:

The nth term of a geometric sequence is

a_{n} = a₁(r)^{n-1}

Given

a₇ = 256 and a₁₀ = 2048 , then

a₁ r^{6} = 256 → (1)

a₁ r^{9} = 2048 → (2)

Divide (2) by (1)

\frac{a_{1}r^{9}  }{a_{1}r^{6}  } = \frac{2048}{256}

r³ = 8 ( take the cube root of both sides )

r = \sqrt[3]{8} = 2

Substitute r = 2 into (1)

a₁ × 2^{6} = 256

a₁ × 64 = 256 ( divide both sides by 64 )

a₁ = 4

Then

a₁ = 4

a₂ = 2a₁ = 2 × 4 = 8

a₃ = 2a₂ = 2 × 8 = 16

a₄ = 2a₃ = 2 × 16 = 32

a₅ = 2a₄ = 2 × 32 = 64
