Oh, dude, the next term in that sequence is 25. You just add 7 each time, like it's no big deal. It's like basic math, man.
31
18 - 6n
21
y = 144/(2n-1) where n is the term in the sequence and y is the number.
15 since you multiply by 3 then subtract 3 in sequence

Subtract -13 at each consecutive term and so the next term will be -34
31
If you mean: 7 18 29 40 then the next term is 40+11 = 51
12, 8
18
18 - 6n
21
It is 4n+2 and so the next number is 18
To find the common ration in a geometric sequence, divide one term by its preceding term: r = -18 ÷ 6 = -3 r = 54 ÷ -18 = -3 r = -162 ÷ 54 = -3
y = 144/(2n-1) where n is the term in the sequence and y is the number.
