Write down in terms of n, an expression for the nth term of the following sequences
a) 25 20 15 10 5

The nth term will be:

Step-by-step explanation:

Given the sequence

25, 20, 15, 10, 5

An Arithmetic sequence has a constant difference 'd' and is defined by

Computing the common difference of all the adjacent terms

As the difference between all the adjacent terms is the same and equal to

Also, the first term is:

Hence, the nth term will be:

       ∵ ,

Therefore, the nth term will be:

d. 9

step-by-step explanation:

in the table given in the picture, x is the input of the function and f(x) is the output on the given input. in the given table, it can be read as the value of function at -3 is it's respective value of f(x) which is -9.

as we have to find the value of f(3), we will see that what is the value of output on input 3. we can see in the table that the output value at x=3 is 9.

so, option d is the correct answer ..

answer: what in the world is this
