-18 then -27
11 is added to each number in the question in turn, the next number will be 49
The answer depends on where, within the sequence, the missing number should have been.
The next number in this sequence should be 33.
18+x=27 calculate and your answer should be 9.
-18 then -27
60.75
This appears to be two interwoven sequences. The first sequence, increases by 9 then 19......7 + 9 = 16........8 + 19 = 27 The second sequence decreases by 8 then 18....16 - 8 = 8........27 - 9 = 18 The next number would thus be 9 + 29 = 38.
9 243 - 81 = 162 81 - 27 = 54 162 = 54 * 3 54 = 18 * 3 27 - 18 = 9
what is the arthmetic sequence of 1 6 3 18 54 27 ? what is the missing terms ?
The nth term of the sequence is (n + 1)2 + 2.
Subtract 2 from the sequence and the answer becomes obvious: 1, 4, 9, 16, 25,...,N2 Now, add the 2 back in: 3, 6, 11, 18, 27,...,(N2+2)

6 12 9 18 15 30 27 54 51
The next number in this sequence should be 33.
11/18 × 27/50 = 33/100
