Answer

Third Term: -1 Seventh Term: 7 Tenth Term: 13

Work Step by Step

To find the third, seventh, and tenth terms, plug in 3, 7, and 10 for n: A(n) = -5 + (n-1)(2) A(3) = -5 + (3-1)(2) A(3) = -5 + (2)(2) A(3) = -5 + 4 A(3) = -5 + 4 A(3) = -1 A(n) = -5 + (n-1)(2) A(7) = -5 + (7-1)(2) A(7) = -5 + (6)(2) A(7) = -5 + 12 A(7) = 7 A(10) = -5 + (10-1)(2) A(10) = -5 + (9)(2) A(10) = -5 + 18 A(10) = 13
