Analyze the following pattern: 1, 2, 5, 10, 17, part i: describe the pattern. (1 point) part ii: what is the 8th term of the pattern? show your work. (1 point)

1 2 5 10 17
+1 +3 +5 +7
+2 +2 +2

2÷2=1 so it begins with n^2

n^2= 1 4 9 16 25
-0 -2 -4 -6 -8
-2 -2 -2 -2

so we have -2n
The pattern is n^2-2n
The 8th term will be 8^2-2x8=64-16=48
