Question

What is the common difference between successive terms in the sequence?

0.36, 0.26, 0.16, 0.06, –0.04, –0.14, ...

Answer 1

difference means 'subtract'

to go from the first term to the second term what do you subtract?

so the difference is MINUS.....

Answer 2

you will also see that you subtract the SAME amount to move to EACH term in the sequence.

This is called an 'arithmetic progression'
