A baker used 2/3 cup of flour to make 1/3 of a recipe. How much flower would the baker use to make the whole recipe?

2 cups

Step-by-step explanation:

cups of flour:  part of a recipe

2/3                         1/3

We want a whole recipe so we need to multiply each part of the ratio by 3

2/3*3                         1/3*3

2                                       1

We need 2 cups of flour for a whole recipe

answer: 40.95

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
