Find the 10th term of the following geometric sequence.<br> 2, 10, 50, 250, ...
defon

Answer:

3906250

Step-by-step explanation:

We can notice that the ratio is 5. 10/2 = 5

Each term gets multiplied by 5 to get the next term.

250 × 5 = 1250 (5th term)

1250 × 5 = 6250 (6th term)

6250 × 5 = 31250 (7th term)

31250 × 5 = 156250 (8th term)

156250 × 5 = 781250 (9th term)

781250 × 5 = 3906250 (10th term)

The 10th term of the geometric sequence is 3906250.

Factor the trinomial 6y squared + 19y + 15
Musya8 [376]

Answer:

1.y = -5/3 = -1.667

2. y = -3/2 = -1.500

Step-by-step explanation:

90    +    -1    =    -91  

     -45    +    -2    =    -47  

     -30    +    -3    =    -33  

     -18    +    -5    =    -23  

     -15    +    -6    =    -21  

     -10    +    -9    =    -19  

     -9    +    -10    =    -19  

     -6    +    -15    =    -21  

     -5    +    -18    =    -23  

     -3    +    -30    =    -33  

     -2    +    -45    =    -47  

     -1    +    -90    =    -91  

     1    +    90    =    91  

     2    +    45    =    47  

     3    +    30    =    33  

     5    +    18    =    23  

     6    +    15    =    21  

     9    +    10    =    19
