Answer:
3 , 1 , -1 , -3
Step-by-step explanation:
5 - 2n
n = 1 ; 5 - 2n = 5 - 2*1 = 5 - 2 = 3
n = 2; 5 - 2n = 5 - 2*2 = 5 - 4 = 1
n = 3; 5 - 2n = 5 - 2*3 = 5 - 6 = -1
n = 4; 5 -2n = 5 - 2*4 = 5 - 8 = -3
First 4 terms are : 3 , 1 , -1 , -3
The expression can be written as:
(2x + 5) - 3
or:
5 + (2x - 3)
