answer is 3263442 ...

ReplyDeletesolution

1 square + 1 = 2

2 square + 2 = 6

6 square + 6 = 42

42 square + 42 = 1806

1806 square + 1806 = 3263442

Agreed.

DeleteEquivalently, each term is the previous term multiplied by one plus the previous term:

1*2=2

2*3=6

6*7=42

42*43=1806

1807*1807=3,263,442

yeah it's too right :)

Delete1806 * 1807 = 3263442

ReplyDeleteIt is always number x( number + 1) so it is: 1806*1807 = 3263442.
