Given:
and 
where 
.
To find:
The explicit formula for the given recursive formula.
Solution:
We know that recursive formula of an AP is:
Where, d is the common difference.
We have,
Here, d=9.
The first term of the AP is .
The explicit formula for an AP is:
Substituting and 
, we get
Therefore, the required explicit formula for the given sequence is .
Hey!

Solution:
= (-18) - (4)
= -18 - 4
= -22
When you subtract a positive to a negative number the end result will always be negative.

Answer:
Total number of choices with a straw: 12
Total number of choices without a straw: 12
Total number of choices: 24
Step-by-step explanation:
Taj has a choice of:
- water, iced tea, or lemonade (3 options)
- with lemon or lime twist (2 options)
- served in a small or large glass (2 options)
This made a total of 3*2*2: 12 different choices
if the drink can be served with or without a straw, he choices are doubled, making a total of 2*12 = 24
Answer:
x=6
Step-by-step explanation:
Ⓗⓘ ⓣⓗⓔⓡⓔ
3(x-1)=15+x
3x-3=15+x
2x-3=15
2x=12
x=6
