Area = Length * Width
6*18 = 6 cm * Width
Width= (6 * 18) / 6 = 18 cm

How do you find the first five terms of a sequence defined recursively

Blizzard [7]

Interesting question. Good to know for computer science.
Suppose you have a function like
an = 3x - 2 Try the first couple
a1 = 3(1) - 2
a1 = 3 - 2
a1 = 1

a2 = 3(2) - 2
a2 = 6 - 2
a2 = 4 So each term differs by 3
a2 - a1 = 3

an = a_(n - 1) + 3
a3 = a2 + 3
a3 = 4 + 3
a3 = 7

a4 = a3 + 3
a4 = 7 + 3
a4 = 10

a5 = a4+ 3
a5 = 10 + 3
a5 = 13

I'll do one more and then check it.
a6 = a5 + 3
a6 = 13 + 3
a6 = 16

a6 = 3x -2
a6 = 3*6 - 2
a6 = 18 - 2
a6 = 16 which checks.

So the general formula is
an = a_(n - 1) * k if you were multiplying or
an = a_(n - 1) + k if you were adding. The key thing is that you are working with the previous term.

The probability that an event will occur is fraction 25 over 25. Which of these best describes the likelihood of the event occur

Zielflug [23.3K]

Answer:

The probability would be certain. This is because $\frac{25}{25}$ simplifies to 1, which would be 100%. If something has a 100% chance of happening, there would be no way it would not occur.
