An arithmetic sequence a starts 2, 5, . .

1 answer:

6 0

Answer:

Tn = 3n-1

T6 = 17

Step-by-step explanation:

Given the arithmetic sequence;

2, 5...

first term a = 2

Common difference d = 5-2 = 3

nth term of an AP is expressed as Tn = a + (n-1)d

Tn = 2 + (n-1)(3)

Tn = 2 + 3n-3

Tn = 3n-1

Get the 6th term

T6 = 3(6)-1

T6 = 18-1

T6 = 17

Hence the 6th term of the sequence is 17

Answer:

111°

Step-by-step explanation:

All these are parallel lines, so the 36° angle is equal to the 36° angle inside the big triangle because they are vertically opposite.

Ignore the line cutting between 45° and the 30° and consider it as one triangle
Add them to get 75°
Now you have two known angles 75° and 36°
To get angle x add 75° and 36° to get 111°
Because x° is an exterior angle and exterior angles equal to the sum of interior angles opposite it inside the triangle.
