Answer:
23
Step-by-step explanation:
put the numbers in numerical order and then cross off on both sides until there is only one number left (look at the process below!)
9,14,16,18,23,25,26,26,30
14,16,18,23,25,26,26
16,18,23,25,26
18,23,25
23
Answers:
The first five terms are: 3, 8, 13, 18, 23
This is a linear sequence
---------------------------------------------------------------------
Explanation:
Plug in n = 1 to get the first term
E(n) = 5*n-2
E(1) = 5*1-2
E(1) = 3
So 3 is the first term
Do the same for n = 2 to get the second term
E(n) = 5*n-2
E(2) = 5*2-2
E(2) = 8
So 8 is the second term
And again for n = 3
E(n) = 5*n-2
E(3) = 5*3-2
E(3) = 13
This means 13 is the third term
And again for n = 4
E(n) = 5*n-2
E(4) = 5*4-2
E(4) = 18
This means 18 is the fourth term
Finally, repeat for n = 5
E(n) = 5*n-2
E(5) = 5*5 - 2
E(5) = 23
So 23 is the fifth term
This sequence is linear because we're incrementing by the same amount each time. In this case, we're adding 5 each time for the sequence 3, 8, 13, 18, 23, and so on.

Answer:
2.7
Step-by-step explanation:
2.7 is not a whole number because it has a decimal behind it. All of the other numbers are whole because they do not.
