The sets A and B are shown below
1 answer:
Answer:
The union of the sets is {-4,-2,0,2,5,10,15}.
The intersection of the sets is {0,10}.
Step-by-step explanation:
means the list elements that you see in either set:
{-4,-2,0,2,5,10,15}.
Notice I didn't list any element twice for occurring in both sets.
means the elements that occur in both set or the elements you see in common between the two if you prefer this wording of the definition:
{0,10}.

Answer:
The nth term of the given sequence tₙ = 3 n - 7
Step-by-step explanation:
Given sequence - 4 , -1 , 2 , 5, 8 , .....
First term a = -4
The difference of two terms of a given sequence
d = -1 - (-4) = -1 +4 = 3
d = 2 - (-1) = 2 +1 = 3
d = 5 -2 = 3
d = 8 - 5 =3
The difference of two terms of a given sequence is equal
∴ The given sequence is in Arithmetic progression(AP)
The nth term of given sequence
<u><em>Final answer:</em></u>-
The nth term of the given sequence tₙ = 3 n - 7
