Joe has $45 dollars and is mowing lawns for $15 per day. Alex is earning 8 dollars per day. How many days will it take for Alex to have more or the same amount as Joe? 8x =45x+15x

8x >45x+15

8x+45≥15x

8x≥45+15x

ab will be equal to

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
