Answer:

x = 5

Step-by-step explanation:

vertical angles are congruent , so

∠ A = ∠ B , that is

5x - 1 = 4x + 4 ( subtract 4x from both sides )

x - 1 = 4 ( add 1 to both sides )

x = 5

What is the 48th term of the arithmetic sequence with this explicit formula?

mariarad [96]

Option B

48th term of arithmetic sequence is -152

<h3>Solution:</h3>

Given that a arithmetic sequence has explict formula,

$a_n = -11 + (n - 1)(-3)$

To find: 48th term of the arithmetic sequence

The nth term of arithmetic sequence can be found by substituting the required value of n in the explict formula

So 48th term of the arithmetic sequence can be found by substituting n = 48 in explict formula

$a_n = -11 + (n - 1)(-3)$

Plug in n = 48

$a_{48} = -11 + (48 - 1)(-3)$

On solving we get,

$a_{48} = -11 + (47)(-3)\\\\a_{48} = -11 - 141\\\\a_{48} = - 152$

Thus 48th term of arithmetic sequence is -152
