Any two numbers can have only one arithmetic mean. If the numbers are x and y, then their arithmetic mean is (x + y)/2.
You take the difference between the second and first numbers.Then take the difference between the third and second numbers. If that difference is not the same then it is not an arithmetic sequence, otherwise it could be.Take the difference between the fourth and third second numbers. If that difference is not the same then it is not an arithmetic sequence, otherwise it could be.Keep checking until you think the differences are all the same.That being the case it is an arithmetic sequence.If you have a position to value rule that is linear then it is an arithmetic sequence.
They are both adjectives. The first relates to geometry and the second to arithmetic.
Two numbers: the first of them is 1 and the second is not!Two numbers: the first of them is 1 and the second is not!Two numbers: the first of them is 1 and the second is not!Two numbers: the first of them is 1 and the second is not!
An arithmetic sequence is a group or sequence of numbers where, except for the first number, each of the subsequent number is determined by the same rule or set of rules. * * * * * The above answer is incorrect. The rule can only be additive: it cannot be multiplicative or anything else.
Succession of numbers of which one number is designated as the first, other as the second, another as the third and so on gives rise to what is called a sequence. Sequences have wide applications. In this lesson we shall discuss particular types of sequences called arithmetic sequence, geometric sequence and also find arithmetic mean (A.M), geometric mean (G.M) between two given numbers. We will also establish the relation between A.M and G.M
They are the first three counting numbers.
Their count. Two in the first case, one in the second.
The difference between two numbers is the second number subtracted from the first number.For example:The difference between 15 and 6 is 915-6=9
There are several options. The first is 200 less than the second. The first is half of the second. The first is the square root of the second when the latter is expressed as a percentage. and others.
The sum of the first five prime numbers is 28. The sum of the cubes of the first three prime numbers is 160. The average of 28 and 160 is 94.
You can use the formula for the sum of an arithmetic sequence for this one. The first odd number would presumably be 1; the interval between one number and the next is 2.
Two odd numbers are said to be consecutive if there are no other odd numbers in between. This happens when the first number is odd, and the second number is two more than the first number.
