8+4+9=21 14+5+2=21 this should be 15+5+2=22 18+1+2=21 this should be 18+1+3=23 the answer is 3 to maintain the sequence, three 3 sets of 3 numbers ,increasing by 1
1
1 x 18, 2 x 9, 3 x 6, 6 x 3, 9 x 2, 18 x 1.
In the sequence 271217, the missing numbers can be determined by analyzing the pattern of the numbers. By looking at the sequence closely, we can see that the missing numbers are 18, 19, and 20. This is because the sequence follows a pattern of increasing by 1 from the previous number. Therefore, the missing numbers after 17 would be 18, 19, and 20 to complete the sequence.
1, 2, 3, 5, 6, 10, 15, 30 None missing.
The first five prime numbers starting from 1 are 1, 2, 3, 5, 7. So 2 is the missing number.
find the missing number 8-4-9 14-5-2 18-1-blank?
1
2
The number progression is n+prime numbers progressively increasing starting from 2. The missing number is 29.
No. That's most of the factors of 18, missing three and six.
-3
c) 17
No. All three are not prime numbers. A prime number is a number that is only divisible by itself and 1. 15 can be divided by 1, 3, 5 and 15 16 can be divided by 1, 2, 4, 8 and 16 18 can be divided by 1, 2, 3, 6, 9 and 18.
The sequence has the formula is 3x - 1 2 → 6 - 1 = 5 5 →15 - 1 = 14 14 →42 -1 = 41 41 → 123 - 1 = 122 The missing number is therefore 41.
Type your answer here... The sequence has the formula is 3x - 1 2 → 6 - 1 = 5 5 →15 - 1 = 14 14 →42 -1 = 41 41 → 123 - 1 = 122 The missing number is therefore 41.
find the missing number 8-4-9 14-5-2 18-1-? i think it's 2 then the sum of all numbers in each set is 21
The factors of 15 are 1, 3, 5, and 15. The factors of 18 are 1, 2, 3, 6, 9, and 18. The common factors of 15 and 18 are 1 and 3.
