The third is because the prove is x = fifteen and if a number is next to a letter, it means multiply, sorry I could only do one.
For an arithmetic sequence, the nth term is the first term plus (n-1)×the differece
the first term is 28, the difference between each adjacent number is 8
so -36=(28)+8(n-1)
8(n-1)=64
n-1=8
n=9
the 9th term is -36
12 1/2 = 12.5
2.5mm = 2.5 cm
So the answer would be 15 cm
