Adding 0.6 each time gives 5.2, 5.8 and 6.4 as the next three numbers.
Adding 255 to 70 gives you a sum of 325. Adding 16 to the sum of 325 gives you a total sum of 341. To verify your answer, you can add the three numbers together on a calculator.
There are 22 such numbers.
Six and three fourths plus four and three tenths equals
In order to find the mean of numbers, add up all of the numbers and thn divide it by the number of numbers there are. Adding two, five and twelve equals nineteen. Then divide three into nineteen, and this gives you a mean of 6.33.
Adding three odd numbers will never equal an even number.
subtract the smallest one
3, 6, 9, 12, 15 and keep adding three till you get to 99.
They don't ! Adding an odd number to two odd numbers always results in an odd number !
Let x, y and z be even numbers. This means that (x + 1), (y + 1) and (z + 1) are all odd. Adding these three odd numbers gives (x + y + z + 3). Because the sum of any number of evens must be even as well - which can be easily proven with idea that where a = 2m and b = 2n, a + b = 2m + 2n = 2(m + n), and is even - adding 3 changes it to an odd number. This holds for any set of three odd numbers. i agree with this... but what about in the form of 2n+1?
Adding three further zeroes (or six, in Comonwealth English usage) to a trillion gives a quadrillion. Adding three further zeroes (or six, in Comonwealth English usage) to a quadrillion gives a quintillion. Adding three (or six) zeroes to a quintillion gives a sextillion. In the more widely used American system, a sextillion is 10 followed by 21 zeroes, while in the Commonwealth English usage, it is equal to 10 followed by 36 zeroes.
