Answer:
.
Step-by-step explanation:
Note: In the given function it should be (n-1) instead of (n=1).
Consider the given function is
It is the explicit form of an A.P.
For 
,
For 
,
Common difference is
The recursive formula of an A.P. is
Substitute 
in the above formula.
Therefore, required recursive formula is .
Answer:
length of arc ≈ 17.8 (to the nearest tenth)
Step-by-step explanation:
To find the length of the arc we use the formula for finding length of an arc.
length of arc = ∅/360 × 2πr
where
∅ = central angle
r = radius
∅ = 340°
r = 3
length of arc = ∅/360 × 2πr
length of arc = 340/360 × 2 × π × 3
length of arc = 340/360 × 6π
length of arc = 2040π/360
length of arc = 204π/36
length of arc = (204 × 3.14)/36
length of arc = 640.56/36
length of arc = 17.7933333
length of arc ≈ 17.8 (to the nearest tenth)
It is a number times its self
