Answer:
34
Step-by-step explanation:
x=3+√8
y =3-√8
now,
1/x^2+1/y^2
=1/(3+√8)² + 1/(3-√8)²
= [(3-√8)²+(3+√8)²] / (3+√8)²(3-√8)² [L.C.M = (3+√8)²(3-√8)² ]
=[(3-√8+3+√8)²-2(3-√8)(3+√8) ] / [(3+√8)(3-√8)]²
=[6²-2.(3²-√8² )] / (3²-√8²)² [ a²+ b²=(a+b)²-2ab]
=[36-2(9-8) ]/ (9-8)²
=[36-2.1] / 1²
=34

Answer:
see below
Step-by-step explanation:
The recursive function tells you the first term is 1. That is the meaning of ...

It also tells you that to find the next term, you multiply this term by 1/2:

And, to find the next term, you multiply this term by 1/2:

Then the first three terms are ...
1, 1/2, 1/4
