Answer 1

Answer:

27

Step-by-step explanation:

We make an explicit equation: f(x)=-1+1/6(x-1)

Now, that's direct 10/3 into the equation!

10/3=-1+(1/6)(x-1)

x=27

Answer 2

Answer:

27

Step-by-step explanation:

-1,-5/6,-2/3,-1/2.........,10/3

you can denote all like, -1 denote a1, -5/6 denote a2, -2/3 denote a3, -1/2 denote a4, .........and 10/3 denote (an). so i am bring out 10/3

[an=10/3] you know formula [an=a1+(n-1) d]

10/3= -1+(n-1/6)

[a, = -1] d= -5/6+1= 1/6 d= 1/6 I have get d

n-1/6= 10/3+1= 13/3 = n-1= 13/3×6= 26

n= 26+1= 27 tum ko nhi pata hoga ki 26+1 kaise keya maine top you see n-1 and I get 1

there are 27 terms in this A. P
