Which expression describes the nth term of the sequence of odd numbers that are greater than or equal to 3

The odd numbers can be given by:

2n - 1 Assuming n is starting at 1.

3 is the second odd number

2(2) - 1 = 4 - 1 =3

If we wish to start at at 3 then we only need to add 1 to the n:

2(n+1) -1 = 2n + 1.

And hence our expression. 

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
