What is the average of the first 2021 positive even integers?

The number 2,021 can be divided by 4 positive divisors (out of which 0 are even, and 4 are odd). The sum of these divisors (counting 2,021) is 2,112, the average is 528.

What is the average of the first 20 positive integers?

10.5
Mean of first 20 natural numbers = Sum of first 20 natural numbers / 20. Hence, we got the mean of the first 20 natural numbers = 10.5.

What is the average of the first positive integers?

Sum of AP is given by, {n * (a + l) /2} [Where a = first term, n = number of terms, l = last term.] = 100 * (1 +100)/2 = 50 * 101. Required Average = (50 *101)/100 = 50.5.

Is 2021 a Semiprime number?

It is a semiprime because it is the product of two primes, and also a Blum integer, because the two primes are equal to 3 mod 4, and also a brilliant number, because the two primes have the same length, and also an emirpimes, since its reverse is a distinct semiprime: 1202 = 2 ⋅601. 22021 is an apocalyptic number.

What is the average of the first 100 positive even integers?

The average or mean of all even numbers 1 to 100 is 51.

What is the average of first 20 multiples of 9?

The average of first 20 multiples of 9 is 94.5.

What is the average of the first 99 positive integers?

50
The average of the first 99 positive integers is 50.

What are the first 100 positive integers?

Here, we have to take the first 100 positive integers. So the series is: 1, 2, 3, 4… 98, 99, 100.

What’s special about the number 2021?

2021 is rather special: it is the concatenation of two consecutive integers (20 and 21) and also the product of two consecutive primes (43 and 47). 2021 is also equal to 33 plus the sum of the first 33 primes. • 2021 = 2(3+23) – 33. 2021 has 4 divisors (see below), whose sum is σ = 2112.

What is the average of the 21 numbers in the list?

There are 21 numbers in the list, and, if we list the numbers in ascending order, the median is the 11th number. Thus, we can let each of the first 10 numbers = 1, each of the next 10 numbers = 10, and the last number = 16. Thus, the average is (10 x 1 + 10 x 10 + 16)/21 = 126/21 = 6.

What is the median of the 21 positive integers?

No payment info required. The greatest of the 21 positive integers in a certain list is 16. The median of the 21 integers is 10. What is the least possible average (arithmetic mean) of the 21 integers?

What is a positive integer less than 100?

So, a positive integer less than 100 can be anything in the sequence: 1, 2, 3, 4, …, 97, 98, 99. An integer is any whole number, such as 1, 5, -7. In other words, it has no decimal points – so 6.5 is not an integer, for example. For it to be positive, it must be bigger than zero.
