Subtract the powers
c. 9-7 so 10^2
d. 8-1 so 5^7
Answer:
a₁ = -5, d = 7, a₂ = 2, a₃ = 9, a₄ = 16
equation of sequence: 
Step-by-step explanation:
a₁ + a₂ + a₃ = 6
a₁ + a₁ + d + a₁ + 2d = 6
3a₁ + 3d = 6
a₁ + d= 2 ⇒ a₁ = 2 - d
a₄ = 16
a₁ + 3d = 16
2 - r + 3d = 16
2d = 14
d = 7
a₁ = 2-7 = -5
a₁ = -5, d = 7 ⇒ a₂ = -5+7 = 2, a₃ = 2+7 = 9, a₄ = 9+7 = 16
equation of arithmetic sequence:
Answer: median is two, mean is two, mode is two, range is 13, the data appears to be symmetrical

Answer:
4.8 Liters
Step-by-step explanation:
Sundaes at her next birthday party. She thinks each person will eat 200 milliliters of ice cream, and there will be 24 people at her party. How many liters of ice cream should she buy
Step 1
1 person = 200ml of ice cream
24 persons = x
Cross Multiply
x = 24 × 200ml of ice cream
x = 4800 ml of ice cream
Step 2
How many liters of ice cream should she buy
We convert from Milliliters to Liters
1 milliliters= 0.001 liters
4800 millilitres = x
Cross Multiply
= 4800 × 0.001 liters
= 4.8 Liters
Therefore, she should buy 4.8 Liters of ice cream
