Answer 1

Step-by-step explanation:

1)

kx²+2x+1=0

if it has real and distinct roots,

b²-4ac>0

2² - 4 (k)(1) > 0

4 - 4k > 0

so, 1 - k > 0

and k < 1

2)

if these terms are in ap, then

second term - first term = third term - second term

(3y +5) - (3y-1) = (5y + 1) - (3y + 5)

6 = 2y - 4

so, y = 5
