He didn’t multiply by 4 first

Answer:

x = 8 (read below for Andre's mistakes)

Step-by-step explanation:

How to actually solve:

1/4(x+12) = 2

1/4(-4+12)=2

1/4(8)=2

How he solves:

1/4(x+12)=2

1/4(x+12)-12=2-12

1/4x=-10

x=-40

So apparently Andre's first mistake is he didn't use PEMDAS. His second mistake was instead of dividing by 4, he multiplied by 4.

Which sequence isn’t a geometric progression?
AVprozaik [17]

Answer: 3, 6, 9, 12

Step-by-step explanation:

A geometric progression has a common ratio.

2,6, 18 and 54 has a common ratio of 3. When you multiply the first number by 3, you get the second number and the same thing applies to the third number.

1, 5, 25 and 125 has a common ratio of 5. When you multiply the first number by 5, you get the second number and the same thing applies to the third number.

4, 8, 16 and 32 has a common ratio of 2. When you multiply the first number by 2, you get the second number and the same thing applies to the third number.

3, 6, 9 and 12 is an arithmetic progression as 3 is added to each number
