Consider the statement "2 is a factor of n2 + 3n."

if n = 1, the statement is "2 is a factor of "
if n = 2, the statement is "2 is a factor of "
if n = 3, the statement is "2 is a factor of "
if n = k + 1, the statement before the algebra is simpliﬁed is "2 is a factor of "
if n = k + 1, the statement after the algebra is simpliﬁed is "2 is a factor of "

4; 15; 28; (k + 1)2 + 3(k + 1); k2 + 5k + 8

4; 20; 28; (k + 1)2 + 3(k + 1); k2 + 5k + 7

4; 10; 18; (k + 1)2 + 3(k + 1); k2 + 5k + 4
