URGENT! S is a geometric sequence.
a) (√x + 1), 1 and (√x - 1) are the first three terms of S.
Find the value of x.
You must show all your working.
x=2
Given the value of x, can someone figure out the next part please?

b) The 5th term of S can be written in the form a √2 + b
where a and b are integers.
Find the value of a and the value of b.

step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
