first term = initial number
second term = initial number + common difference
third term = initial number + 2(common difference)
So...
2x+5-(x+4) = common difference
4x+3-(2x+5) = also common difference
2x+5-(x+4) = x+1
4x+3-(2x+5) = 2x-2
Because x+1=2x-2 we can solve for x.
x=3
So the sequence goes... 7,11,15...
19 is the fourth term
2 x 2 x 5 x 5 x 5
2^2 x 5^3
I think it is 2.67 but i might be wrong
Answer:
Step-by-step explanation:
24 hours x 60 min x 60 seconds
3600 seconds x 24 = 86400 seconds
If the number of trials is changed the number of experimental outcomes also changes
