Arithmetic Sequences; Finding the Common Difference

Instructed by Ty'Asia & Erica

WORDS TO KNOW

An arithmetic sequence is a sequence in which each term after the first differs from the proceeding term by a constant amount.

The common difference of an arithmetic sequence is the difference between consecutive terms of the sequence.

Examples

4, 9, 14, 19, 22, 27... d= 19 - 14 = 5

-6, -14, -22, -30, -38,... d= -30 - (-22) = -8

152,002; 152,195; 152,388; 152,581; 152,674;... d= 152,388 - 152,195 = 193
