Answer:
a) The missing terms are 9, 13, 21 and 25.
b) If we know that
and
, then the n-th term of the sequence is represented by
.
Step-by-step explanation:
a) Given that elements of the sequence are found by increasing by the same amount, we infer that elements are part of an arithmetical progression. The rate of progression is now determined:



The missing terms are:








The missing terms are 9, 13, 21 and 25.
b) The formula for the arithmetical progression is represented by the following formula:
(1)
Where:
- First element of the sequence.
- Indicator associated with the element of the sequence.
- Progression rate.
If we know that
and
, then the n-th term of the sequence is represented by
.
7/18 of the flowers are red roses
because 5/12 are yellow, the rest would be red. so 7/12. but total roses are only 2/3 of the whole garden.
tip: when you see "of" in a fraction problem, it means you can multiply them.
so, 7/12 OF 2/3 is just (7/12) * (2/3).
multiplying straight across and simplifying will get you to 7/18!
Okay. So, based off of that, if you divide 1 1/2 (3/2) by 3/4, 3/2 * 4/3 is 12/6 or 2. 1/2 cups of raspberries is needed for each fourth of the cake. 1/2 * 4 = 2. Lin will need 2 cups of raspberries for the whole cake.
