1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, … these are the
Fibonacci numbers.
so add in +1,
we get
1+1,1+1,2+1, 3+1 ,5+1, 8+1 ,13+1, 21+1, 34+1, 55+1 ...........
2,2,3,4,6,9,14,22,35,56.........
so 22,35,56 is the answe

The width of the walkway is 3 feet, If the area of the garden is 484
and the area covered by both the garden and the walkway (the entire square) is 784
.
Step-by-step explanation:
The given is,
Area of the garden is 484 
Area covered by both the garden and the walkway (the entire square) is 784
.
Let, x - Width of the walkway
Step:1
Formula to calculate area of square is,
...........................(1)
Where, r - Radius of square
Step:2
For garden,
A = 484 
Equation (1) becomes,

Take square root on both sides,

a = 22 feet
For garden and the walkway (the entire square),
A = 784 
Equation (1) becomes,

Take square root on both sides,

a = 28 feet
Step:3
Ref attachment,
Side of garden and the walkway =
Side of garden + 2 (width of the walkaway)....(1)
28 = 22 + 2 ( x )
2 ( x ) = 28 - 22
= 6

Width, x = 3 feet
Result:
The width of the walkway is 3 feet, If the area of the garden is 484
and the area covered by both the garden and the walkway (the entire square) is 784
.
Your answer would be 70
10 divided by 3=3.33
3.33 times 21= 70
-5/10 and in simplest form it would be -1/2
