An=a1+d(n-1)
an=nth term
a1=first term, when n=1
d=common differnce=amount each term increases by
n=which one
so
when n=1, an=40
so a1=40
it seems to increas by 7 each time
an=40+7(n-1)
explicit formula is expanded
an=40+7n-7
an=33+7n is the formula
the domain is natural numbers because you can't have the -3rd term or the 0th term or the 3.24th term
domain is natural numbers
the formula is

Answer: Height of the water is 20 cm.
Step-by-step explanation:
Since we have given that
Base area = 100 square cm
volume of vase shaped like an octogonal prism = 2 liters
We need to find the height of water.
and 1 liter = 1000 cm³
2 liters = 2×1000 cm³
As we know the formula for "Volume":
Hence, height of the water is 20 cm.
