Answer: 2n^2+3n-4
1st differnce is 3, 7, 11, 15
2nd differnce is 4
so its 2n^2
we compare it to teh 2n^2 sequence
2 8 18 32 50
-1 2 9 20 35
difference is 3, 6, 9, 12,15
so it is 3n-4
Perpendicular = opposite sign and reciprocal slope
-4 slope turns into 1/4
Y = 1/4x + b
11 = 1/4(-16) + b
11 = -4 + b, b = 15
Solution: y = 1/4x + 15

Step-by-step explanation:
Your welcome
*I'll be keeping the solutions in exact form*
So firstly, square root both sides. This will split the equation into two:
Next, add 1 on each side: 
Next, divide 3 on both sides, and your answers will be
