16 plus 10 plus 8 plus 6 plus 2 is equal to 42.
The sequence is xn = xn-1 + 2
10 - 4n
2 + 6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 = 106
2 + 5 is 7 + 6 =13 + 7 = 20 + 8 = 28 + 9 = 37 + 10 is 47.
2+4+8+2+10+6 = 6+8+2+10+6 = 14+2+10+6 = 16+10+6 = 26+6 = 32
10 + 2 - 6 = 6
16 plus 10 plus 8 plus 6 plus 2 is equal to 42.
The differences betweent the consequent members are: 48, 24, 12, 6 - the next is equal to the previous divided by two. So the next difference will be 6:2 = 3 and the next member of the sequence will be 10 - 3 = 7
9 + 6 - 2 + 7 - 10 = -4
The sequence is xn = xn-1 + 2
10 - 4n

correct!! 2 plus 2 does equal 4!! yay u!!

30. 2+3+5=10, 4+6=10, and 2+4+1+1+2=10.
3 + 5 + 6 + 9 + 2 + 1 + 10 = 36
