An integer, x = 160 is added by a random number, n, ten times. Where n can be 1 - 10. The probability of n ≤ 5 is 50%, and it will increase by 5% for every subsequent increase of 5 to the integer.
The probability of n > 5 is 50%, and it will decrease by 5% for every subsequent increase of 5 to the integer.

Find the probability of the integer, x ≥ 200. ​​​

25% is the answer

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for
