Write down in terms of n 4 ,1 -2, -5 ,-8

aₙ= 3n+1

Step-by-step explanation:

4 ,1 -2, -5 ,-8

AP with a₁=4 and d= -3

aₙ= 4+3*(n-1)= 4+3n-3= 3n+1

aₙ= 3n+1

step-by-step explanation:

i dont really.know

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)
