Answer

Therefore, the second term is 2, the fourth term is -4, and the eleventh term is -25.

Work Step by Step

The given equation is: A(n) = 5 + (n - 1)(-3) Second term:: n=2 Sub in 2 for n in the equation A(2) = 5 + (2 - 1)(-3) A(2) = 2 Fourth term:: n=4 Sub in 4 for n in the equation A(4) = 5 + (4 - 1)(-3) A(4) = -4 Eleventh term:: n=11 Sub in 11 for n in the equation A(11) = 5 + (11 - 1)(-3) A(11) = -25 Therefore, the second term is 2, the fourth term is -4, and the eleventh term is -25.
