Answer: The common difference is 8
Step-by-step explanation:
First Use the formula for the second to generate the first two numbers.
= 2^3n-2
Put in 1 for the first term and you will get 2 and the second term is 16 and to get from 2 to 16 you will multiply by 8.
1: 3 and 2/5
2: 8 and 1/2
3: 2 and 13/20
4: 2 and 4/5
5: 3 and 9/10
6: 8 and 4/5
7: 3 and 92/100
3 and 46/50
8: 6 and 69/100
9: 6 and 7:50
10: 9 and 1/10
11: 10 and 11/100
12: 7 and 1/5
13: 10 and 23/100
14: 5 and 1/5
Answer: y = 2x + 9
<u>Step-by-step explanation:</u>
slope(m) =
=
=
= -2
Point-Slope formula: y - y₁ = m(x - x₁)
y - 5 = -2(x - 2)
y - 5 = -2x + 4
y = 2x + 9
