2n(n+1)
2n-1
24 - 6n
The nth term is (36 - 4n)
Give the simple formula for the nth term of the following arithmetic sequence. Your answer will be of the form an + b.12, 16, 20, 24, 28, ...
2n(n+1)
8 + 4n
24 - 6n
The nth term is (36 - 4n)
Give the simple formula for the nth term of the following arithmetic sequence. Your answer will be of the form an + b.12, 16, 20, 24, 28, ...
2n(n+1)
8 + 4n
If 3 is the first term, then the nth term is [ 3 x 2(n-1) ] .
If 3 is the first term, then the nth term is [ 3 x 2(n-1) ] .
7n - 4
If you mean: 6 12 18 24 then the nth term is 6n
The nth term of that series is (24 - 6n).
The nth term is 7n-4 and so the next number in the sequence is 31
The nth term in the arithmetic progression 10, 17, 25, 31, 38... will be equal to 7n + 3.
