The properties of the mathematical sequence allow us to find that the recurrence term is 1 and the operation for each sequence is
a) Subtraction
b) Addition
c) AdditionSum
d) in this case we have two possibilities
* If we move to the right the addition
* If we move to the left the subtraction
The sequence is a set of elements arranged one after another related by some mathematical relationship. The elements of the sequence are called terms.
The sequences shown can be defined by recurrence relations.
Let's analyze each sequence shown, the ellipsis indicates where the sequence advances.
a) ... -7, -6, -5, -4, -3
We can observe that each term has a difference of one unit; if we subtract 1 from the term to the right, we obtain the following term
-3 -1 = -4
-4 -1 = -5
-7 -1 = -8
Therefore the mathematical operation is the subtraction.
b) ...
In this case we can see more clearly the sequence when writing in this way
each term is found by adding 1 to the current term,
Therefore the mathematical operation is the addition
c)
The recurrence term is unity, with the fact that the sequence extends to the right and to the left the operation is
- To move to the right add 1
-
- To move left subtract 1
Using the properties the mathematical sequence we find that the recurrence term is 1 and the operation for each sequence is
a) Subtraction
b) Sum
c) Sum
d) This case we have two possibilities
- If we move to the right the sum
- If we move to the left we subtract

The sum of all the measurements is just the average times the number.
So if the average of all 92 is 7 the sum of those is
The average of the last two is 7.2 so their sum is
That means the sum of the first 90 is
so the average of the first 90 is
cm
So if the average of all 92 is 7 the sum of those is
The average of the last two is 7.2 so their sum is
That means the sum of the first 90 is
so the average of the first 90 is
