Question

If Y belongs to all integer , find the solution set of 2000 -4 (2y - 1) ‹ 2000​

Answer 1

Answer:

The sequence of integers starting from 1 to 1000 is given by

1,2,3,4,...,1000

The above sequence has 1000 terms. The first term is 1 and the last term is 1000 and the common difference is equal to 1.

We have the formula that gives the sum of the first n terms of an arithmetic sequence knowing the first and last term of the sequence and the number of terms (see formula above).
