39. The rule here is starting with the number 9, add (-6 + sequence number * 6). 9 + (-6) = 3 3 + 0 = 3 3 + 6 = 9 9 + 12 = 21 21 + 18 = 39 39 + 24 = 63
The next number in the sequence 3-15-6-30-21 is -207.
21 = 3 x 7 39 = 3 x 13 So 21 and 39 are not relatively prime as they are sharing a common factor: 3
The next number is -21
21: (3)+3=(6)+4=(10)+5=(15)+6=(21)
39. The rule here is starting with the number 9, add (-6 + sequence number * 6). 9 + (-6) = 3 3 + 0 = 3 3 + 6 = 9 9 + 12 = 21 21 + 18 = 39 39 + 24 = 63
The next composite number after 38 is 39. It is divisible to 3 and 13 in addition to 1 and 39.
4x-39 = 2x+3, 4x-2x = 42 x=21
The next number in the sequence 3-15-6-30-21 is -207.
The GCF is 3.
To express the number 39 as a product of prime factors, we first identify that 39 is an odd number. We can start by dividing 39 by the smallest prime number, which is 2. Since 39 is not divisible by 2, we move on to the next prime number, which is 3. Dividing 39 by 3 gives us 13, which is a prime number. Therefore, the prime factorization of 39 is 3 x 13.
39
1, 3, 7, 21 1, 3, 13, 39
The GCF is 3.
21 = 3 x 7 39 = 3 x 13 So 21 and 39 are not relatively prime as they are sharing a common factor: 3
GCF(21, 39) = 3.
the next number is 21 because it is adding the last number stated.
