In an Arithmetic Progression, if d = -4, n = 7, an = 4, then find a1

Step-by-step explanation:

Arithmetic progression:

The nth term of an arithmetic progression is given by the following equation:

In which is the first term and d is the common difference between consecutive terms.

In this question, we have that:

We want to find . So

We have that

  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.
