Answer:
a. 10, 16
b. 211, 311
c. 10 , 12.5
d. -13, -22
Step-by-step explanation:
In an arithmetic sequence, there is a constant difference, which is the difference between a term and the previous term. We find the constant different for each sequence, and we add it to the second term to find the third term. Then we add the constant difference to the third term to find the fourth term.
a.
4 - (-2) = 6
3rd term: 4 + 6 = 10
4th term: 10 + 6 = 16
b.
111 - 11 = 100
3rd term: 111 + 100 = 211
4th term: 211 + 100 = 311
c.
7.5 - 5 = 2.5
3rd term: 7.5 + 2.5 = 10
4th term: 10 + 2.5 = 12.5
d.
-4 - 5 = -9
3rd term: -4 + (-9) = -13
4th term: -13 + (-9) = -22
Answer:
95
Step-by-step explanation:
10th term of the sequence is 95.

Answer:
The length of each of the 4 sides of a square is the same. Then
5x - 8 = 3x
2x = 8
x = 4
5(4) - 8 = 12
3(4) = 12
The length of each side is
L = 4.
The perimeter is 4 times the length.
P = 4L = 4(4) = 16
