If you mean: 2 4 8 16 32 64 it is 2^nth term and so the next number is 128
There is no pattern
7/8
t(n) = t(n - 1) + (10n - 9)
56 + 64 = 120
The GCF of 56, 60, and 64 is 4.
If you mean: 2 4 8 16 32 64 it is 2^nth term and so the next number is 128
Had it not been for 64, the nth term would be given by t(n) = 3*n2 However, this cannot be the case because then t(4) would have been 48, not 64.
n3
42
There is no pattern
square of (n x 2)
even numbers between 50 and 64= 52, 54, 56, 58, 60, & 62
The pattern for the nth term is n3. Therefore, the fourth term in the sequence is equal to 43 = 64.
7/8
The nth term in the sequence means an unspecified number an unspecified distance along the series. 8 16 32 64 128... n. It is also a shothand notation so the reader knows that the sequence continues.
t(n) = t(n - 1) + (10n - 9)
