Chapter 11 - Section 11.2 - Arithmetic Sequences - Exercise Set: 15

Answer

The first six terms are: $-0.4, -2.0, -3.6, -5.2, -6.8, -8.4$

Work Step by Step

The next five terms f the sequence can be found by adding the common difference to obtain: $a_1=-0.4 \\a_2=-0.4+(-1.6) = -2.0 \\a_3 = -2.0+(-1.6) = -3.6 \\a_4 = -3.6+(-1.6) = -5.2 \\a_5 = -5.2 + (-1.6) = -6.8 \\a_6 = -6.8 + (-1.6) = -8.4$
