1 the m-th number of the n-th row is (expressed by an algebraic expression containing N, and N ＞ m) 2 3 4 the number 2002 in line 2001 should be 5 6 7 8 9 10 11 12 13 14 15 16 ……

1 the m-th number of the n-th row is (expressed by an algebraic expression containing N, and N ＞ m) 2 3 4 the number 2002 in line 2001 should be 5 6 7 8 9 10 11 12 13 14 15 16 ……

According to the observation, each row has the number 2N-1 (n is the number of rows.)
Then there are (n-1) ^ 2 numbers in line n-1, that is, (n-1) ^ 2 + 1 in line n, and (n-1) ^ 2 + m in line M
The number in line 2001 and line 2002 should be 2000 ^ 2 + 2002 = 4002002

Looking for rules in mathematics, junior high school
If the sequence A1, A2, A3, A4 An, starting from the second term, the constant of the ratio of each term to the previous term is Q, then an=_______ If the constant Q is not equal to 1, then A2 + A2 + a3 + an=________ (expressed by an algebraic expression containing A1, Q, n)
It's due tomorrow. It's urgent

An is equal to the N-1 power of A1 times Q
Equal to A1 (the nth power of 1-Q) / (1-Q)
