How to describe the relationship between terms Example • Look at first and second terms. • Subtract first term from second term • How much are you adding to the previous term??? 8, 13, 18, 23… First term = 8 Second term = 13 13 - 8 5 Adding 5 to pervious term
Finding the next three terms in the sequence Example • Find the last term of our sequence. • Fellow our description to find new last term • Repeat • Repeat 8, 13, 18, 23… Last term is 23 Adding 5 to pervious term 23 + 5 = 28 28 + 5 = 33 33 + 5 = 38
a. 4, 7, 10, 13 b. 1.0, 1.3, 1.6, 1.9… c. 2.5, 3.0, 3.5…
