42, each number in the sequence is the addition of the previous two: 2-2-4-6-10-16-26 2+2=4 4+6=10 6+10=16 10+16=26 16+26=42
12, 14, 16
14 18 20
the patter is -2 +3 -4 +5 -6 +7 so it goes 8 6 9 5 10 4 11 3 12 2 11 1 10
7 4 6 5 5 4...
10, 8, 6, 4, 2, 0, -2, -4
20
3
The next number is 34 Thus: 3 1 4 2 6 4 10 8 18 16 34 (Note: 3 + 1 = 4 : 4 + 2 = 6 : and so on)
4, 6, 8, 10, 12
10
42, each number in the sequence is the addition of the previous two: 2-2-4-6-10-16-26 2+2=4 4+6=10 6+10=16 10+16=26 16+26=42
Set up the equation and solve for x: 2/3(x) - 6 = -10 (next add 6 to each side to separate knowns from unknowns) 2/3(x) = -4 (next multiply both sides by 3 to simplify) 2x = -12 (next divide both sides by 2 to solve for x) x = -6 to prove: substitute x with -6 (hint: 2/3 of -6 = -4) 2/3(-6) - 6 = -10 -4 - 6 = -10 -10 = -10
30 is the next number. Times 3, then minus 2.
-4 - 6 = -10
Ignoring the "9" , then this is a Fibonacci sequence. 2,2,4,6,10 The first two terms are 'seed' terms then successive terms equal the sum of the two previous terms. 2 + 2 = 4 2 + 4 = 6 4 + 6 = 10 The next term would be 6 + 10 = 16.
