Question

How is the pattern changing to get from one term to the next ? -48, -44, -40, -36, -32, . . .

Answer 1

The given pattern is

$-48,-44,-40,-36,-32$

We will find the difference between the consecutive terms

$\begin{gathered} -44-(-48)=-44+48=4 \\ -40-(-44)=-40+44=4 \\ -36-(-40)=-36+40=4 \\ -32-(-36)=-32+36=4 \end{gathered}$

Then the pattern is increasing by 4 units

The pattern is changing by adding 4
