It is 1 9 2 8 3 7 4 6 5 5 : 1 + 9 = 10 2 + 8 = 10 3 + ? = 10 ----> 3 + 7 = 10
1 10 2 9 3 8 4 7 5 6 6 5 7 4 8 3 9 2 10 1
divide by 2 and add 1
It is 7
1+2+3+4 = 10 ---------------------- For this question there is actually a whole lot of answers... for example: ((1 + 2) + 3) + 4 = 10 ((1 × 2) × 3) + 4 = 10 (1 + 2) + (3 + 4) = 10 1 + (2 + 3) + 4 = 10 1 × (2 × 3) + 4 = 10 1 + ((2 + 3) + 4) = 10 1 × ((2 × 3) + 4) = 10 1 + (2 + (3 + 4)) = 10 ((1 + 2) + 4) + 3 = 10 (1 + 2) + (4 + 3) = 10 So Manny Diffrent way's you can use four numbers to equal 10.
t(n) = 3(n-1) + 1, for n = 1, 2, 3, etc
Seperate like this: 2 1 2 3 2 6 2 10 2 ? then categorize them two by two: 2 1 2 3 2 6 2 10 2 ? now this is the question : 1 3 6 10 ? and the answer is 15" 1 + 2 = 3 ---> + 3 = 6 ----> + 4 = 10 ----> + 5 =15
It is 1 9 2 8 3 7 4 6 5 5 : 1 + 9 = 10 2 + 8 = 10 3 + ? = 10 ----> 3 + 7 = 10
A regular decagon; A 20-gon with 2 lots of 10 congruent sides and angles in an alternating pattern; A 30-gon with 3 lots of 10 congruent sides and angles in an 1-2-3-1-2-3 pattern; A 40-gon with 4 lots of 10 congruent sides and angles in an 1-2-3-4-1-2-3-4 pattern; etc.

7 is the next number in the pattern

The full series should be: {1, 3, 6, 10, 12, 12, 10, 6, 3, 1} It is nothing more than a series that increases in a certain way & then decreases in the exact opposite way. You can see this by using subtraction as follows: 3-1 = 2 6-3 = 3 10-6 = 4 12-10 = 2 12-12 = 0 12-10 = 2 10-6 = 4 6-3 = 3 3-1 = 2 Notes: - the series pattern increases to 12 in this way: 2, 3, 4, 2 - the series pattern then decreases from 12 in the exact opposite way: 2, 4, 3, 2 - if graphed with time as the x-coordinate & each number as the y-coordinates, the full series would resemble a curve that looks similar to a hill with a flat top.
t(1) = 3 t(n) = t(n-1) + 2(n-2) for n = 2, 3, 4, ...
