What is the next term of the geometric sequence? 2,-10,50, ?

-250

Step-by-step explanation:

Each thing is multiplied by -5.

The next term of the geometric sequence is -250

Step-by-step explanation:

Formulas:-

nth term of geometric sequence

aₙ = aₙ₋₁ * r

r - Common ratio

r = aₙ/aₙ₋₁

It is given a geometric sequence, 2,-10,50

To find the common ratio

r = aₙ/aₙ₋₁

we have , a₁ = 2 and a₂ = -10

r = a₂/a₁ = -10/2 = -5

To find the next term

Here next term is a₄

a₄ = a₃*r

a₃ = 50

a₄ = 50 * (-5) = -250

Therefore the next term is -250

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
