The sequence given is an arithmetic sequence where the first term is 3 and the common difference is 6 (each term increases by 6). The nth term of an arithmetic sequence can be calculated using the formula: ( a_n = a_1 + (n-1) \cdot d ), where ( a_1 ) is the first term and ( d ) is the common difference. For the 50th term: ( a_{50} = 3 + (50-1) \cdot 6 = 3 + 294 = 297 ). Thus, the 50th term is 297.

The factors of 21 are: 1, 3, 7, 21.The factors of 27 are: 1, 3, 9, 27.The common factors are: 1, 3
They are members of the set of numbers of the form 21*k where k is a positive integer which is less than 143.
the anser is that you are stupid
3 is a multiple of 15, 21, and 27.
after -9 it is -15 then -21, -27 and the ninth is -36
The LCM of 15, 21 and 27 is 945.
The least common multiple of 19 , 15 , 27 , 21 = 17,955
15 = 3 x 521 = 3 x 727 = 3 x 3 x 3hcf of 15 and 21 is 3lcm of 15 and 21 = 15 x 21 / 3 = 105hcf of 105 and 27 = 3lcm of 105 and 27 = 105 x 27 / 3 = 945
The Least Common Multiple (LCM) of (15, 21 and 27) is 945.

55 + 34 + 31 + 27 + 21 + 21 + 20 + 17 + 15 + 15 = 256
The number at the midpoint of these two numbers is (15 + 27)/2 = 21
A single number, such as 1521273339 does not define a sequence. There is no nth term for a signle number.
