The series of these numbers are arithmetic progression because every time you subtract the next term to the previous term, each difference is common (or constant), that 2 - 7 = -5, or -3 - 2 = -5.

You can use the formula of the arithmetic term, that is
an = a1 + (n - 1)d
where an = nth term, a1 = first term, n = number of terms, d = common difference

The 14th term will be
a(14th term) = 7 + (14 - 1)*(-5) = -58

Which table has greater constant of proportionality?
marissa [1.9K]

The table with greater proportionality is table 3.

<h3>What is constant proportionality?</h3>

The constant of proportionality is the ratio between two directly proportional quantities.

As, the constant proportionality is

k= y/x

For table 1,

k = 1/1 = 2/2 =1

For table 2,

k = 6/1= 12/2 = 2

For table 3,

k = 5/1 = 10/2 = 5

For table 4,

k = 4/1 = 8/2 = 4

Hence, table 3 is with greater proportionality.

<h3>What is Function?</h3>

Generally, Function is simply defined as a connection between two or more variables that may be expressed mathematically.

In conclusion,  Functions with graphs that never touch or cross the x-axis are said to have complicated roots, not real ones.
