-18 then -27
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.
12, 8
-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.
6 12 9 18 15 30 27 54 51
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.
The answer depends on where, within the sequence, the missing number should have been.
The next number in this sequence should be 33.
11/18 × 27/50 = 33/100
18+x=27 calculate and your answer should be 9.
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)
