Which sentence is NOT a geometric progression?
DIA [1.3K]

<u>c) 3, 6, 9 12</u>  is NOT a geometric progression

<h3>Further explanation </h3>

Geometry sequences are series of numbers that have a constant ratio

or can be interpreted:

Each number is obtained by multiplying the previous number by a constant

The sequence can be:

a, ar, ar², ar³, ... etc.

Can be formulated

\large {\boxed {\bold x_n = ar ^ {n-1}}}

where:

a is the first term, and

r is the common ratio

So we have to see the series has the same ratio or not

a. \dfrac{5}{1}=\dfrac{25}{5}=5\to \rm geometric\:progression

b. \dfrac{8}{4}=\dfrac{16}{8}=2\to \rm geometric\:progression

c.\dfrac{6}{3}\neq \dfrac{9}{6}\to \rm not\:geometric\:progression

d. \dfrac{6}{2}=\dfrac{18}{6}=3\to \rm geometric\:progression

Answer:

25. a = 60

26. a = 17

Step-by-step explanation:

In these two problems we are going to use a property of parallelograms that says: opposite angles have equal measure

so we have

25.

6a+10=130\\\\6a=130-10\\\\6a=120\\\\a=60

and for 26 we have

4a-4=2a+30\\\\4a=2a+30+4\\\\4a=2a+34\\\\4a-2a=34\\\\2a=34\\\\a=17
