Answer:
Rows 126
last row has 41
last row is not full because its an odd number
Step-by-step explanation:
<span>The first quartile (Q1) is defined as the middle number between the smallest number and the median of the data set.</span>
First term (a) = -15
common difference(d)= -9-(-15)
= -9+15=6
So,
12th term(a12)= a +(n-1)d
= -15+(12-1)×6
= -15 + 11×6
= -15+66
= 51
The answer is C.
90/105=6/7
