Answer:
96 m
Step-by-step explanation:
16m x 12m= 192
192/2=96
3-x=5
3+ -x= 5
-3 -3
__________
-1x=2
÷-1 ÷ - 1
______________
x= -2
x= -2 is the answer
The sequence is, in fact, quadratic. It is described by the equation
.. a[n] = (n*(n -1))/2 +2
First differences are increasing, so the sequence will not be arithmetic. An arithmetic sequence has constant first differences.
Second differences are constant, so the sequence will not be geometric. A geometric sequence will have first-, second-, third-differences, and those to any level, that have the same constant ratio as the terms of the original sequence.
