Probably there are different possible answers for this. I would say 15, because it isn't a Prime number.
25-1=24 24-2=22 22-3=19 19-4=15 15-5=10 The next number in the series is 10.
19 every other number is a 6 and every number inbetween goes up by 5
Reverse the operations. Start with 19, subtract 4, which leaves 15. Divide 15 by 3, and that is the number you began with.
11
the Answer is 15.. all the numbers are prime numbers and cannot be divided by any number except 1 and the number itself. but the number 15 is divisible by 1, 3, 5 and 15 so the odd number is 15
19 doesn't belong. The rest of the numbers are multiples of 3.
4 more than 15 is 4 + 15 = 19.
"You Belong To Me" by Jo Stafford was the number 1 hit song on September 19, 1952.
15 is composite number 17, 19 and 23 are prime numbers.
Country code +880 is Bangladesh, and +880 19 is a Banglalink mobile.
Prime and odd are the only ones I could think of
3 x 5 = 15, so 15 is not a prime number.
19
15 and 19/100
25-1=24 24-2=22 22-3=19 19-4=15 15-5=10 The next number in the series is 10.
19 only has 2 factors - itself and 1. 15 has 4 factors - itself, 1, 3, and 5. Prime numbers can only have 2 factors. 19 is prime, 15 is composite.
An atom with 15 electrons and 19 neutrons has an atomic number of 15, which corresponds to phosphorus (P). The atomic mass can be calculated by adding the number of protons (15) and neutrons (19), resulting in a mass number of 34. Therefore, this atom is a phosphorus isotope with a mass number of 34, commonly denoted as (^{34}\text{P}).
