1 17/18 or 35/18

Step-by-step explanation:

First you have to make the 1/2 and 5/9 common denominators, which would be 10/18 and 9/18 then you simply just subtract 3 9/18 and 1 10/18 to get 1 17/18.

Hope this helps!

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
