Answer:
When n=3 and x=−2 the answer is 11.
Step-by-step explanation:
Given:
Let p (n,x) be the function such that

To Find:
p (n,x) = p ( 3, -2) = ?
Solution:

Substituting n = 3 and x = -2 we get

Negative square gives positive number therefore (-2)²=4


When n=3 and x=−2 the answer is 11.
3.556 is the correct answer
2.
EXPLANATION:
If g= 3 we can replace g with 3.
Now we have h-5 x 3
and if h= 17, we can replace h with 17.
Now we have 17 - 5 x 3.
because of pemdas, multiplication is first
5 x 3 is 15,
17 - 15 is 2.

Answer:
(a) 498501
(b) 251001
Step-by-step explanation:
According Gauss's approach, the sum of a series is
.... (1)
where, n is number of terms.
(a)
The given series is
1+2+3+4+...+998
here,



Substitute
,
and
in equation (1).



Therefore the sum of series is 498501.
(b)
The given series is
1+3+5+7+...+ 1001
The given series is the sum of dd natural numbers.
In 1001 natural numbers 500 are even numbers and 501 are odd number because alternative numbers are even.



Substitute
,
and
in equation (1).




Therefore the sum of series is 251001.
