To get from 4 to 12, you use the following formula. 12 = (4 squared)/2 + 4.

Continue on with (X^2)/2 + X.

So (84^2)/2+84=3612

4 == 1 2 2 4

take last two ( 2 & 4)--->> (2+1)*4==12

12 == 1 2 3 4 6 12

take last two (6 & 12)----> (6+1)*12==84

84 ==1 2 ......... 42 84

take last two (42 & 84)----> (42+1)*84== 3612

correct me if i m wrong plzzzzzzzzzzzzzzzzz....

4 12 84 252
exp-
4 12 84 252
*3 *7 *3 *7
4 to 84 is the multiplication of 3,7 i.e 21
same from 12 to 252 is *7*3=21
21*12=252

Aaditya Raj  (4 years ago)

Here,term being squared is from the product of last pair, and a number one less to that term is subtracted from it.

As, in first term we have 4×3=12

So for next,squaring of 3,subtracted by a number one less i.e. 2= 3^2-2=9-2=7

So 12×7=84,similarly for next term to obtain squaring of 7 and subtracted by 6, we get 43

84×43=3612
