Given:
First term of an arithmetic sequence = 5
Second term = 3
To find:
The explicit formula for the given arithmetic sequence.
Solution:
We have,
First term: 
Second term: 
Common difference is



Now, the explicit formula for an arithmetic sequence is

where, a is first term and d is common difference.
Putting a=5 and d=-2, we get

It can also be written as


Here, n is an integer greater than or equal to 1.
Domain is the set of input values.
Therefore, the explicit equation is
or
and domain is all interest greater than or equal to 1.
No 2/3 is not equivalent to 5/6
please can i have a brainliest
Answer: -57
Step-by-step explanation:
15 + ( - 72)
Distribute
15 - 72
When this happens, you subtract the smaller number by the bigger one, then put the sign that was on the bigger number on what you get.
72 - 15 = 57
Put a negative sign on 57
-57
15 + (-72) = -57
X=11
All you have to do is add 5 to both sides and then divide by 5 on both sides
