Find the nth term of the quadratic sequence 4,7,12,19,28

answer:

The first differences are 3, 5, 7, 9 and the second differences are 2.

Hence, the first term of the sequence is n^2 (since half of 2 is 1).

Subtracting n^2 from the sequence gives 3, 3, 3, 3, 3.

So putting these two terms together gives n^2 + 3.

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
