1.Take any number. Now multiply it by 2, 3, 4————- at every step. Also add 3 to it at each step. Look at the difference in the answer. Is it the same at every step? 12 x 2 + 3 = 27 12 x 3 + 3 = 39 12 x 4 + 3 = 51 12 x 5 + 3 =63 12 x + 3 =—————- ———–x 7 + 3 =————
Ans.12 x 6 + 3 = 75 12 x 7 + 3 = 87 12 x 8 + 3 =99 12 x 9 + 3 =111 . In every case the difference between consecutive numbers is 12
