Step-by-step explanation:
this sequence is geometric not arithmetic
HOw we know that ??
when we get a common difference that must Be equal
d=6-2=4 not equal to d=18-6=12
So it is not arithmetic
but when we get the common ratio that also must be equal
r=6/2=18/6=54/18=3 equal
So it is geometric
By using this equation:
a(n)=a(1)*r^(n-1)
and we have a(1)=2 , r=3
<u>Explicit rule:</u> a(n)=2*(3)^(n-1)
<u>Recursive rule:</u> a(n)= r * a(n-1)
a(n-1) ⇒ priviuse term
SO: a(n)= 3 * a(n-1)
For example:
a(3)= 3 * 6 =18
<em>I really hope this helps <3</em>
Answer is the third one. It is the only answer where all points work in the equation.

Answer:
Therefore the value of 
Step-by-step explanation:
Given:
m∠ A = 56°
m∠ B = 75°
m∠ ACD = x°
To Find:
x = ?
Solution:
In Δ ABC
An exterior angle of a triangle is equal to the sum of the opposite interior angles.
Here,
The opposite interior angles are angle A and angle B.
An exterior angle of a triangle is angle ACD which is x°
∴
...Exterior angle property of Δ
Substituting the values we get

Therefore the value of
