2^2=4, 4 - 1=3, 3^2 = 9, 9 - 1= 8, 8^2= 64, 64 - 1= 63.

So its the first number squared, then subtracted by 1, then that number is squared, then subtracted by 1, etc.

You are multiplying each number in the sequence by -2. Therefore, the next number in the sequence after 32 is -64.


The number 64 is the next logical number in the following sequence of numbers 2,6,14,30... True or false?

2,6,14,30,.... The difference between each pair of numbers is ;) 4,8,16,....= 2^2 , 2^3, 2^4 So the next number is 2^5 = 32 Hence x - 30 = 32 x = 32 + 30 = 62 The next number in the sequence. The next number would be 2^6 = 64 Hence x - 62 = 64 x = 62 + 64 = 126 !!!! So the sequence would read 2,6,14,30,62,126,....

6 21 40 63 90 121 what is the rule for this sequence?

(1) Take the difference of the two previous numbers in sequence (2) Add 4 to this difference. (3) Take the number from step #2 and add it to the previous number in the sequence. For example, to find the next number in the sequence: (1) 121 - 90 = 31 (2) 31 + 4 = 35 (3) 121 + 35 = 156
