In the sequence 400, 200, 150, 75, 25...... what number comes next
Scorpion4ik [409]

Answer:

The next term in the sequence = -175

Step-by-step explanation:

Here, the given sequence is : 400, 200, 150, 75, 25...

Now here, in the given sequence,

First Term - Second Term = 400 - 200 = 200

Second Term -   Third Term   =  200  - 150  = 50

Third term  - Fourth Term  = 150 - 75   = 75

Fourth term - Fifth term = 75 - 25 =  50

So, following this pattern,

Fifth Term - Sixth term = 200

Or, 25 - Sixth Term = 200

or, Sixth term  =  25 - 200  = - 175

Hence, the next term in the sequence = -175

Solve the following system of equations: −2x + y = 1 −4x + y = −1
Liula [17]
Hello!

-2x + y = 1
-4x + y = -1

You can subtract these equations from each other to eliminate y

2x = 2

Divide both sides by 2

x = 1

Put this into one of the original equations

-2(1) + y = 1

Combine like terms

-2 + y = 1

Add 2 to both sides

y = 3

The answer is D) (1, 3)

Hope this helps!
