Step-by-step explanation:

Sylvia bought 4 bananas for 50 cents each and 1 apple for 80 cents. What was the total cost of all the fruit?

Amanda sold 5 Pokemon cards with 3 duplicate. One costs 3.00, the next costs 5.50, and the last one costs 2.25. If she sold all 15 cards, how much money would she make?

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
