Mean median of 30,37,42,44,44,46,49,52

Mean=43 Median=44

Step-by-step explanation:

To find the median add up all the numbers and divide by however many numbers there are. To find the median look at the middle number if there is not one then add the two in the middle and divide by two. Hope this helps

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

answer for #1 is c

answer for #2 is d
