Question

Write the next two integers in each of the following sequences:

$18,14,10,6,............$

Answer 1

Step 1: Taking the difference of the consecutive numbers

$$\begin{gathered} 14-18=-4 \\ 10-14=-4 \end{gathered}$$

From the sequence, it is clear that the numbers are decreasing by $4$

Step 2: Finding the next consecutive numbers.

So, the next numbers are

$$\begin{gathered} 6-4=2 \\ 2-4=-2 \end{gathered}$$

Hence, the sequence is $18,14,10,6,2,-2$
