1 -1, 2 -2, 3 -3, 4 -4, and so on. It is simply a positive number followed by its negative number.
You add the 2 numbers before e.g. 2+3=5
The answer is (no.) x3 = (no. 2) - 1 = (no. 3) x3= (no.4) x4 and so on... 1 x 3 = 3 - 1 = 2 x 3 = 6 - 1 = 5 x 3 = 15 - 1 = 14 x 3 = 42 - 1 = 41. :D Hope i helped
The pattern is 1 2 3 4... etc and so the next number will be 29
12 ****************************** 11, 16, 22 are the 3 numbers continuing the pattern.
plus 4, minus 3
t(n) = 3(n-1) + 1, for n = 1, 2, 3, etc
1:2:3:5:8:5:3:2:1
Start at 1. Multiply by 3. Subtract 1. Multiply by 3. Subtract 1. Repeat this pattern.

You add the 2 numbers before e.g. 2+3=5
this series increments in powers of 3 like 1+3^0=2 2+3^1=5 5+3^2=14 14+3^3=41 and so on....
You start with two integers, usually 0 and 1 or 1 and 1 and get the next number in the pattern by adding the two previous numbers. For example starting with 1 and 1 , 1 + 1 = 2 ,so the sequence is now 1 1 2 1+ 2 = 3 , so the sequence is 1 1 2 3 2+3 = 5 . " " " " 1 1 2 3 5 The formula is an = an-1 + an-2. where a0 and a1 are given and n > 1.
The answer is (no.) x3 = (no. 2) - 1 = (no. 3) x3= (no.4) x4 and so on... 1 x 3 = 3 - 1 = 2 x 3 = 6 - 1 = 5 x 3 = 15 - 1 = 14 x 3 = 42 - 1 = 41. :D Hope i helped
