For every 6kg of a child's weight, pediatricians prescribe 7mg of fever reducer. If Greg weighs 42kg, how many milligrams of the fever reducer will the pediatrician prescribe?

49mg

Step-by-step explanation:

lets consider 6kg as x for a second. First we need to find how many x's are in 42kg. 6kg=1x so to find the correct amount of x's we need to divide 42 by 6. You would get 7. Multiply 7 by the 7mg and yo would get 49. This is what it would look like with working:

6kg=x or 1x

42/6=7

Now we have 7x's

7x7=49                    

49mg

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
