The table shows the number of servings for different size cakes at Mimiy's bakery suppose a high school graduation expected 2,889 guests how many X-large sheets Cakes should the school order? explain how you solved.

24

Step-by-step explanation:

From the table given, at Mimi's Bakery, 1 X-Large sheet cake size will give us a number of servings of 120.

To find out how many X-Large cake size the school should order, simply divide the number of expected expected guests by the number of servings the X-Large cake will do.

Given that the score is expecting 2,889 guests, the school should order for:

2,889 ÷ 120 = 24.075 X-Large cakes.

Let's just say, an estimated 24 X-Large size cake should be ordered.

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
