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
