Answer:
The n th of the given sequence is 
Step-by-step explanation:
<u>Step 1</u> :-
Given sequence is 20,14,8,2,.......this sequence in arithmetic progression but this sequence is decreasing sequence.
given first term is 20 and difference is
now the nth term of given sequence is
by using formula 
final answer:-
<u>verification</u>:-
put n=1 we get first term is 20
put n=2 we get second term is 14
put n=3 we get third term is 8
put n=4 we get fourth term is 2
so the n th term of sequence is
Answer:
x = 110°
Step-by-step explanation:
Given that AB = AD then Δ ABD is isosceles and the base angles are congruent, that is
∠ ABD = ∠ ADB = 35°
The sum of the 3 angles in the triangle = 180°, that is
x + 35° + 35° = 180°
x + 70° = 180° ( subtract 70° from both sides )
x = 110°

Step-by-step explanation:
Answer:
B) irrational
Step-by-step explanation:
<em>It can not be imaginary</em>, because imaginary numbers are √(negative number).
<em>It can not be rational</em>, because the cube root of 11 can not be displayed as a repeating or ending number (it's 2.22398009... by the way).
The only option is irrational.
