What is the d value in the following arithmetic sequence 7 2
What is the d value in the following arithmetic sequence? -7, -2, 3, 8, .
Solution
t
he given arithmetic sequence is -7, -2, 3, 8, .
The d value or the common difference is the difference between any two consecutive terms in an arithmetic progression.
To find the common difference, subtract a pair of terms. It doesn\'t matter which pair is picked, as long as they are right next to each other:
-2-(-7)=-2+7=5
3-(-2)=3+2=5
8-3=5
The difference is always 5.
So, d=5.
