Given sequence: 
6,2,-2,-6,-10,...
First we have to find the common difference.
d= 2-6=-4
d=-2-2=-4
d=-6-(-2)=-6+2=-4
So common difference is -4.

Which means it is an arithmetic sequence.

Formula for the given sequence is:
an= a1+ (n-1)d
an=6+(n-1)(-4)
an=6-4n+4
an=-4n+10

Answer: an=-4n+10

Hey there,

Your question states: <span>Which choice is the simple formula for the nth term of the following arithmetic sequence?

</span><span>6, 2, -2, -6, -10, 6, -6, 10

If you see,(6,2) are 4 apart. And also (-2,-4) So this would include that (-10,6) because they are also 4 apart.

Hope this helps.

The bits are determined by repeated division by 2 to yield either 0 or 1.
 
183/2 = 91 rem 1  =>  1  (lowest bit)             2⁰
  91/2 = 45 rem 1  =>  1 (next higher bit)     2¹
  45/2 = 22 rem 1 => 1  (next higher bit)     2²
  22/2 = 11 rem 0  => 0 (next highrt bit)      2³
    11/2 = 5 rem 1    => 1 (next higher bit)     2⁴
     5/2 = 2 rem 1   => 1 (next higher bit)     2⁵
     2/2 = 1 rem 0   => 0 (next higher bit)    2⁶
     1/2 = 0 rem 1   => 1 (next higher bit)      2⁷
The next higher 24 bits have 0 in each bit.

For 32-bit system,
183 = 00000000 00000000 00000000 10110111 (with a space between bytes for readability)

Answer: 00000000000000000000000010110111

A recipe for sabayon calls for 2 egg yolks, 3 tablespoons of sugar, and 1⁄4 cup of white wine. After cracking the eggs, you star
Annette [7]

Answer:

Step-by-step explanation:

A recipe for sabayon calls for 2 egg yolks, 3 tablespoons of sugar, and ¼ cup of white wine. After cracking the eggs, you start measuring the sugar, but accidentally put in 4 tablespoons of sugar. How can you compensate?

Note that we put  in 4/3 more sugar than we wanted, because 3(4/3) = 4

So we need to increase eveything else by 4/3

So 2(4/3)  = 8/3  = 2 +2/3 egg yolk    and      (1/4)(4/3) =4/12 = 1/3 cup of wine

A = 1/ 7 - 4√3<br> B = 1/ 7+ 4√3<br> Find....<br> A) a² + b²<br> B) a³ + b³
iragen [17]

The value of a2+b2 = 0.05

The value of a3+b3 = 41.73

Concept: (a+b)2 = a2+b2+2ab

(a-b)2 = a2+b2-2ab

(a+b)3 = a3+b3+3a2b+3ab2

(a-b)3 = a3-b3-3a2b+3ab2

(I) a²+b²=(1/7-4✓3)²+(1/7+4✓3)²

⇒ ( 1/49 - 48) +(1/49 + 48)=(1-2352/49) + (1+2353/49)

⇒ -47.97 +48.02= 0.05

(ii) a³+b³=(1/7-4✓3)³+(1/7+4✓3)³

⇒(-6.78)³ +(7.07)³

⇒-311.66 +353.39= 41.73
