Question

Thanks been trying for ages

Answer 1

x₁ = 3,29296875

x₂ = 3,276659786

x₃ = 3,279420685

Explanation:

This is a recurrent relationship between xₙ₊₁ and xₙ

To get x₁, write the formula with n=0:

`x_1 = 3+ (3)/(x_0^2)`

Then fill in what you know, x₀=3.2. This gives you x₁.

Repeat for n=1,... and so forth.

Excel can do this effectively, see picture.
