Determine the recursive formula
The given sequence shows arithmetic progression (AP).
First, we calculate the common difference (d):


The recursive formula of an AP is determined using:
where 
Substitute 3 for d

Answer:
He multiplied 25 by 1 and then multiplied 25 by 9 correctly. He added the two partial products correctly
Step-by-step explanation:
Use the distance formula: d² = (x₂ - x₁)² + (y₂ - y₁)²
d² = 50² + 80²
= 2500 + 6400
= 8900
d = √8900
= 94.3
Answer: 94.3 km
Answer:
4
Step-by-step explanation:
The x coordinate is the same so the distnce is only the difference in y
5 - 1 = 4
Answer:
Cost of 12 pencils = 37 4/5 = 189/5
Cost of 1 pencil = 189/5 ÷ 12
= 189/5 x 1/12 = 189/60 = 63/20 = 3 3/20
So required answer is 3 3/20
