Answer:
y = 3^(x + 1).
Step-by-step explanation:
Here the y values are increasing by a factor 3 and when x = 0 y = 3,
so y = (3)^1 when x = 0 - that is y = (3)^(0 + 1) = 3.
So y = 3^(x + 1) is the rule.
Check: when x = -2, y = 3^(-2+1) = 3 ^-1 = 1/3.
When x = 1, y = 3(1+1) = 3^2 = 9.
Let, the number = n
It would be: 2n = 28
n = 28/2
n = 14
In short, Your Answer would be 14
