Answer:
= - x^2 + 4x - 14
Step-by-step explanation:
(2x^2+6x−7)−(3x^2+3x−1)+(x−8)
= (2x^2+6x−7 ) −3x^2 -3x +1 + (x−8)
= (2x^2+6x−7 ) −3x^2 -3x +1 + x−8
= (2x^2+6x−7 ) −3x^2 -2x - 7
= 2x^2+6x−7 −3x^2 -2x - 7
= 2x^2+6x−7 −3x^2 -2x - 7
= - x^2 + 4x - 14

The complete sequence solved by arithmetic progression is 5 8 11 14 17.
<h3>What is arithmetic progression?</h3>
The difference between every two successive terms in a sequence is the same; this is known as an arithmetic progression (AP). It is possible to obtain a formula for such nth term of a AP using this kind of development.
The numbers 5, 8, 11, 14,... belong to the arithmetic progression (AP) since they follow a pattern in which the previous number is added by 3 to get each new number.
nth term = a + (n-1)d
where, a is the initial term (=5)
n is the total terms in the series (=5)
d is the common difference (8-5=3)
Substitute the values in the formula to get the result;
5th term = 5 + (5-1)3
= 5 + (4×3)
5th term = 17
Therefore, the last term (5th term) of the series is 17.
