State If This Is Geometric Or Not:, 100,-50,25,25/2

State if this is geometric or not:
100,-50,25,25/2

 

Answer: the sequence is a not geometric sequence

Step-by-step explanation:

A geometric sequence can be determined if it has a constant number being multiplied to the next terms of the sequence or the common ratio.

At can be determined by dividing the preceedinging term to the previous term

-50÷100= -1/2

25÷ (-50)= -1/2

25/2÷25= 1/2

Since the there was no common ratio in the sequence because of the differences in the qoutient, it is not a geometric sequence.

A Gas Collected When The Pressure Is 1.5 Atmosphere Has A Volume Of 2.300ml. How Much Volume Will It Occupy With A Pressure Of 1.7 Atmosphere At Const

A Gas collected When The Pressure is 1.5 Atmosphere has a volume of 2.300ml. How Much volume will it occupy with a pressure of 1.7 atmosphere at constant temperature?   Good Day Problem: A Gas collected When The Pressure is 1.5 Atmosphere has a volume of 2.300ml. How Much volume will it occupy with a pressure of 1.7 atmosphere at constant temperature? Given Data: V₁ (initial volume) = 2.3 ml P₁ (initial pressure) = 1.5 atm V₂ (Final volume) = ? unknown P₂ (final pressure) = 1.7 atm Solution: This problem can be solve using Boyles Law formula which is P₁V₁ = P₂V₂ To solve for V₂,  we can use the formula V₂ = P₁V₁ / P₂ V₂ = P₁V₁ / P₂     = 1.5 atm × 2.3 ml /  1.7 atm   (cancel the unit atm)     = 3.45 ml / 1.7     = 2.03 ml Answer: The final volume is 2.03 ml
