Answer:

150

Step-by-step explanation:

The terms in the sequence form an arithmetic sequence with n th term

$a_{n}$ = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 2 and d = 3 , thus

2 + 3(n - 1) = 449

2 + 3n - 3 = 449

3n - 1 = 449 ( add 1 to both sides )

3n = 450 ( divide both sides by 3 )

n = 150

Answer:

x= 10

Step-by-step explanation:

If line m is parallel to line n,

(8x +50)°= 130° (corr. ∠s, m//n)

8x +50= 130

Bring constants to one side:

8x= 130 -50

8x= 80

Divide both sides by 8:

x= 80 ÷8

x= 10
