Answer:
Object 1 is the heaviest object.
Step-by-step explanation:
The first column of the table tells you ...
Object 1 is heavier than the 10 kg weight
The second column of the table tells you ...
Object 2 weighs 10 kg
The third column of the table tells you ...
Object 3 is lighter than the 10 kg weight
Then the relative weights are ...
Object 1 > Object 2 > Object 3
That is, Object 1 is the heaviest object.
We have an arithmetic progression:
Nth=an
an=a₁+(n-1)d
a₁ is the first term.
n=number of terms.
d=common difference
10,17,24,31...
a₁=10
d=a₂-a₁=17-10=7
Therefore:
Nth=an
an=a₁+(n-1)d
an=10+(n-1)7
an=10+7n-7
an=7n+3.
Therefore: the formula for the nth is, an=a+(n-1), in this case; an=7n+3,
To check:
a₁=7*1+3=10
a₂=7*2+3=17
a₃=7*3+3=24
a₄=7*4+3=31
a₅=7*5+3=38.......
1/2 of the cake was eaten
1+2=3. 3/6=1/2
All the slices are the same size
