for some reason would not let me post the summation right
using weak induction
n
e i = (n(n+1))/2
i=1
(a) (1 point) show that p(1) is true, which completes the base case.
(b) inductive step:
i. (1 point) what is your inductive hypothesis?
ii. (1 point) what are you trying to prove?
iii. (2 points) complete the proof:

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
