If you means, total 3 digit numbers, then that wouldbe 9*10*10 as 0 cant come at first place, so 9 and in other two places, all 10 digits can be placed. total = 900.
To count a triplet in a sequence of numbers, look for three consecutive numbers that are the same. Count how many times this pattern occurs in the sequence.
The number of inversions in a sequence of numbers is the count of pairs of elements that are out of order.
Three.
Three of them ... the binary numbers 3, 5, and 6. 011 101 110
In many countries, they are used to break up large numbers into smaller strings: of three or two digits to make them easier to read.
A single number, such as 1531513 does not define a sequence. Furthermore, according to Wittgenstein's Finite Rule Paradox every finite sequence of numbers can be a described in infinitely many ways and so can be continued any of these ways - some simple, some complicated but all equally valid.
You can use sequences ending in every number from 3 to 25 so 23 times.
There are 500 of 3-digit numbers begin with an odd one (100-199, 300-301, 500-599,700-799, and 900-999). In terms of "how many strings of", may filter or expand the above answer.
It is a sequence of numbers that represents how many spheres you would have in a pyramid of different heights.
How many strings of three digits are there? 000 to 999, or a total of 1000. How many strings of three digits contain the same three digits? That's 000, 111, 222 ... 999! ten in total. The difference is your answer: 1000-10 = 990.
Pianos have three strings per note... Therefore - since most modern pianos have 88 keys, they have 264 strings.
you add up all the numbers in the sequence then divde your answer by how many numbers there are in the sequance so if you had the numbers 20, 19, 7, 45, 2 you would add them up which equals 93 then divide it by 5 (how many numbers in the sequence) so your answer would be 18.6
