Answer:

3 is the missing answer.

Step-by-step explanation:

7 * 3 = ( _ * 3) + ( 4 * 3)

21 = ( _ * 3) + 12              -Multiply 4 * 3 and 7 * 3

9 = _ * 3                          -Divide both sides by 3

3 = missing number

What is the common ratio for the sequence 5,-10,20,-40?
algol [13]

Answer:

The COMMON RATIO of the sequence is -2.

Step-by-step explanation:

Here, the given sequence  is:

5, -10, 20 ,-40

Here, The first term ( a 1 ) of the sequence is (5)

The second term (a 2) of the sequence is (-10)

Third term of sequence (a 3) is 20

Now, calculating the common ratio (r) of sequence ,we get:

\frac{a_2}{a_1} =  r  = (\frac{-10}{5}) = -2\\\frac{a_3}{a_2} =r  = (\frac{20}{-10}) = -2

So, here r =(-2)

⇒ The COMMON RATIO of the sequence is -2.

Hence, the given sequence in in GEOMETRIC PROGRESSION.
