Find P 20 of the following arithmetic sequence: 206, 212, 218, 224....
Yanka [14]

Answer:

p_{20} = 1.25528

P₀ = 206 and difference d = 6

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that the arithmetic sequence

                 206,212,218,224,.....

P₀ = 206 and difference d = 212-206 = 6

The n^{th} term of the sequence

   t_{n} = ar^{n-1}

<u><em>Step(ii):-</em></u>

The n^{th} term of the sequence

   P_{n} = ar^{n-1}

Put n=20

P_{20} = 206 ( 6) ^{20-1}

p_{20} = 1.25528

The ages of three children in a family can be expressed as consecutive integers. The square of the age of the youngest child is
tensa zangetsu [6.8K]

Answer: 10, 11, & 12

<u>Step-by-step explanation:</u>

Let x represent the age of the youngest child.  

Their ages are consecutive so,

Youngest: x

Middle: x + 1

Oldest: x + 2

The age of the Youngest squared (x²) equals 8 times the Oldest [8(x + 2)] plus 4.

x² = 8(x + 2) + 4

x² = 8x + 16 + 4

x² = 8x + 20

x² - 8x - 20 = 0

(x - 10)(x + 2) = 0

x - 10 = 0     or      x + 2 = 0

  x = 10       or          x = -2

Since age cannot be negative, x = -2 is not valid

So, the Youngest (x) is 10

the Middle (x + 1) is 11

and the Oldest (x + 2) is 12

If Y= 9, is the inequality true or false? Y + 3 &lt; 12
Serjik [45]

Answer:

False

Step-by-step explanation:

To solve this problem, plug in the value for Y, 9, into the inequality.

9 + 3 < 12

Now, solve the inequality. Evaluating 9 + 3, the equation becomes:

12 < 12

12 is not less than 12 (12 = 12), therefore the answer is false.
