Answer:
a_n = 28-2n
Step-by-step explanation:
Given sequence is:
26,24,22,20
We can see that the difference between consecutive terms is same so the sequence is an arithmetic sequence
The standard formula for arithmetic sequence is:
Here,
a_n is the nth term
a_1 is the first term
and d is the common difference
So,
d = 24-26
= -2
a_1 = 26
Putting the values of d and a_1
Hence, the recursive formula for given sequence is: a_n = 28-2n ..

Question:
Three students were working on 630,000÷700 in math class.
a. Desiree finds the quotient is 9,000 and Micah finds the quotient is 900.
Determine which student found the correct quotient.
b. Delilah finds her answer is 90, but she copied the expression incorrectly from the board. If her reasoning and answer for the expression she copied are correct, what expression might she have written?
Answer:
a. Micah is correct
b.
Step-by-step explanation:
Given
Solving (a): Who is correct?
To do this, we first calculate the quotient of the expression.
Divide 630000 by 700
Hence:
Micah is correct
Solving (b): What Delilah must have copied?
We have:
There are no options to pick from. So, we just need to work out expressions that equals 0.
Possible expressions are:
Answer:
29
