Answer: -7
Step-by-step explanation:
- The common difference of an Arithmetic progression is the difference between any two consecutive terms.
i.e. for sequence [tex]a_1, a_2, a_3 ,.....[/tex]
Common difference = [tex]d=a_2-a_1=a_3-a_2=a_4-a_4[/tex]
The given sequence : 56, 49, 42, 35, ...
Then , Common difference =[tex]49-56=-7[/tex]
Hence, the common difference for the given sequence. =-7
