$18/3 = 6
$

Therefore the common ratio is 6.

30. The average of a list of 4 numbers is 92.0. A new list

klasskru [66]

Answer:

H. 94.0

Explanation:

The original list: $a _1$ $a _2$ $a _3$ $40$

The new list: $a_1$ $a_2$ $a_3$ $48$

$\frac{a_1+a_2+a_3+40}{4} =92$

$a_1+a_2+a_3=92$ × $4-40=328$

$\frac{a_1+a_2+a_3+48}{4} =\frac{328+48}{4} =94$
