Find the next three terms of the following sequence.

(ii) 5, 1,-3,…

Solution :

Pattern :

By subtracting 4 from the 1st term, we get second term. By subtracting 4 from 2nd term, we get 3rd term.

4th term = -3 - 4 = -7

5th term = -7 - 4 = -11

6th term = -11 - 4 = -15

Hence the next three terms are -7, -11, -15.
