The sequence given is -2, 4, -8, 16, which can be observed as alternating signs with each term being a power of 2 multiplied by -1. The nth term can be expressed as ( a_n = -2 \times (-2)^{n-1} ), or equivalently, ( a_n = -2^n ) if you account for the sign change. Thus, the nth term formula is ( a_n = -2^n ).
The Nth term in the series is [ 2N ] .
2n
If you mean: 2 4 8 16 32 64 it is 2^nth term and so the next number is 128
The nth term is equal to 4n.
It is: -6n+22
The Nth term in the series is [ 2N ] .
2n
If you mean: 2 4 8 16 32 64 it is 2^nth term and so the next number is 128
The nth term is 22n and so the next number will be 5*22 = 110
The nth term is equal to 4n.
It is: -6n+22
[object Object]
square of (n x 2)
The nth term is: 3n+1 and so the next number will be 16
The given sequence is a geometric sequence where each term is multiplied by 2 to get the next term. The first term (a) is 4, and the common ratio (r) is 2. The nth term of a geometric sequence can be found using the formula ( a_n = a \cdot r^{(n-1)} ). Therefore, the nth term of this sequence is ( 4 \cdot 2^{(n-1)} ).
The nth term is (2n - 12).
the nth term for 1 2 4 8 16 32 is 2 to the power n-1. I cannot type superscript. It look like a big 2 and then n-1 where we put small number on the top right hand.
