How to simplify arithmetic explicit formulas to general linear form? an= 7+5(n-1) as an example

an = 5n + 2

Step-by-step explanation:

an = 7 + 5(n - 1)

an = 7 + 5n - 5

an = 5n + 2

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
