Question

Pr = 2 +5n
then find p (2) + P (-2)-p(17.​

Answer 1

Answer:

p(n)=2+5n.

p(2)=2+5(2).

=2+10.

=12.

p(-2)=2+5(-2).

=2-10. (Because +×-=-).

=-8. (Because +×-=- & largest number is important).

p(17)=2+5(17).

=2+85.

=87.

p(2)+p(-2)-p(17)=12+(-8)-87.

=12-8-87. (Because +×-=-).

=4-87. (Because +×-=-).

=-83. (Because +×-=- & largest number is important).

I think this is your answer.

Answer 2

Answer:

$\huge{\boxed{\rm{\red{Answer=-83}}}}$

Step-by-step explanation:

Given that :-

P(n)=2+5n

If n=2, then

P(2)=2+5(2)

=>P(2)=2+10

=>P(2)=12

If n=-2 then

P(-2)=2+5(-2)

=>P(-2)=2-10

=>P(-2)=-8

If n=17 then

=>P(17)=2+5(17)

=>P(17)=2+85

=>P(17)=87

Now,

P(2)+P(-2)-P(17)

=>12+(-8)-87

=>12-8-87

=>12-95

=>-83

The value p (2) + P (-2)-p(17) is -83
