There is a string of numbers 1, 7, 13, 19, 25 The 1000th number in this column is______ ．

There is a string of numbers 1, 7, 13, 19, 25 The 1000th number in this column is______ ．

This sequence is an arithmetic sequence whose first term is 1 and tolerance is 6. The 1000th term is: 1 + (1000-1) × 6, = 1 + 999 × 6, = 1 + 5994, = 5995

A column of numbers in a row, 1,1,2,3,5,8,13 Starting from the third number, each number is the sum of the two numbers before it, and the 143rd number is an odd even number

The rule of this sequence is odd, odd, even, odd, odd, even, repeat all the time
143 / 3 = 47 plus 2, so the 143rd number is odd
