Answer:
sorry but the question isn't clearly understandable!! maybe Post the full question
The pattern is that every 2 numbers are a pair, the first being any selected number, and the second number next to is the number times 3.
3 x 3 = 9
4 x 3 =12
7 x 3 = 21
Therefor we type 16 x 3 = 48
48 is your next number.
Y+8 = -3(x-7)
Distribute the -3
y +8 = -3x +21
Subtract 8 from both sides
Y = -3x +21 -8
Y= -3x+13
