Find the common difference for the arithmetic sequence. -55, -50, -45, -40

5

Step-by-step explanation:

Just grap any two consecutive terms in the sequence. lets say -55 and -50

-50-(-55) = 5

you can check this by picking two other terms

An explicit formula for an arithmetic sequence with common difference d is given by an=a1+d(n−1) a n = a 1 + d ( n − 1 ) . An explicit formula can be used to find the number of terms in a sequence.
