Question 2 of 5 Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.
Match each explicit formula to its corresponding recursive formula,

Given:

The different recursive formulae.

To find:

The explicit formulae for the given recursive formulae.

Solution:

The recursive formula of an arithmetic sequence is and the explicit formula is , where a is the first term and d is the common difference.

The recursive formula of a geometric sequence is and the explicit formula is , where a is the first term and r is the common ratio.

The first recursive formula is:

for .

It is the recursive formula of an arithmetic sequence with first term 5 and common difference 5. So, the explicit formula for this recursive formula is:

Therefore, the correct option is A, i.e., .

The second recursive formula is:

for .

It is the recursive formula of a geometric sequence with first term 5 and common ratio 3. So, the explicit formula for this recursive formula is:

Therefore, the correct option is F, i.e., .

The third recursive formula is:

for .

It is the recursive formula of an arithmetic sequence with first term 5 and common difference 3. So, the explicit formula for this recursive formula is:

Therefore, the correct option is D, i.e., .

step-by-step explanation:

i could only see the first page. the other pages were blurry. ; -;

x hot dogs for 2$, y drinks for 3$. 29 items and total 70

2x+3y=70

x+y=29

if x=17and y=12

2(17)+3(12)=70

34+36=70
