Prove that the following sets are equivalent {1, 2, 3, 4, 5, 6.....}, (2, 4, 6, 8, 10,...) (1,3,5, 7, 9,...), {1, 4, 9, 16, 25...)

If (5+9+13+...... n terms)/( 7 + 9 + 11 +....(n+1) terms) = 17/16 , then n=

9 + 7 = 16 " " 9+1 = 9+6=15 " " 9+0 = 9+5 = " " 9-1= 9+4 = " " 9-2= 9+3 " " 9+(-3)= 9+2= When you added a positive integer, in which direction did you move on the number line?

9 + 7 = 16 " " 9+1 = 9+6=15 " " 9+0 = 9+5 = " " 9+(-1)= 9+4 = " " 9+(-2)= 9+3 " " 9+(-3)= 9+2= When you added a negative integer, in which direction did you move on the number line?

If (5 + 9 + 13 + .... rarr nterms) / (7 + 9 + 11 + ... rarr (n + 1) terms) = (17) / (16), then n =
