The missing number is 34. The progressive difference between the numbers doubles:
4 + 2 = 6
6 + 4 = 10
10 + 8 = 18
18 + 16 = 34
34 + 32 = 66
961526412
The next number in the sequence is... 360.

This is an arithmetic sequence with t1 = 1 and the common difference d = -18.The nth term of an arithmetic sequence is given by the formula:tn = t1 + (n - 1)d (substitute 10 for n, 1 for t1, and -18 for d)t10 = 1 + (10 - 1)(-18) = 1 + 9(-18) = 1 - 162 = -161Thus the 10th number of the sequence is -161.
The missing number is 18
The difference between the numbers is increasing by 2 every time. Therefore, 18 + 9.5 = 27.5 is the next number in the sequence.
The number which best completes the sequence below is: 2 9 5 13 10 19 17 ?
18
what is the arthmetic sequence of 1 6 3 18 54 27 ? what is the missing terms ?
It seems that each number is calculated from the previous one by multiplying, first with 1, then with 2, then with 3, etc.
