What are the next three terms of the following are arithmetic sequence: 13,24,35...

46, 57, 68.

Step-by-step explanation:

13 + 11 = 24 + 11 = 35

35 + 11 = 46 + 11 = 57 + 11 = 68

2nd one in the first row is correct

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
