Answer 2

12 24 42

12 64 96

18 32 72

Solution:

Given that,

12 24 42

12 64 96

18 32 ?​

We have to find the missing term

Let us analyse the pattern followed

Take first row

12   24   42

12 = 1 + 2 = 3 -------- (i)

24 = 4 - 2 = 2--------- (ii)

42 = 2 + 4 = 6------- (iii)

See that, from (i) and (ii)

3 x 2 = 6 which we got in (iii)

Similarly,

12   64   96

12 = 1 + 2 = 3 -------- (i)

64 = 6 - 4 = 2 --------- (ii)

96 = 9 + 6 = 15 = 1 + 5 = 6 ------- (iii)

See that, from (i) and (ii)

3 x 2 = 6 which we got in (iii)

Similarly,

18 = 1 + 8 = 9

32 = 3 - 2 = 1

Now,

9 x 2 = 18 = 1 + 8 = 9

Thus two digit number that gives 9 is 72

7 + 2 = 9

Thus we get,

12 24 42

12 64 96

18 32 72
