Answer 1

• First iteration: m = 1
m = m(m+1) = 1(1+1) = 2
m++ (Now m = 3)

• Second iteration: m = 3
m = 3(3+1) = 12
m++ (Now m = 13)

• Third iteration: m = 13
m = 13(13+1) = 182
m++ (Now m = 183)

183 doesn't satisfy the condition.

Answer 2

Loop runs 1 time m=(1+1)×1=2
Then m++ so m = 3
Loop runs 2 time m=(3+1)×3=12
m++ = 13
Loop runs 3 time m=(13+1)×13=182
m++ = 183
183 > 20 so loop terminates there
