Correct answer:31Explanation:Let d be the common difference, and let x be the second term. The first three terms are, in order, x−d,x,x+d.

Correct answer:31Explanation:Let d be the common difference, and let x be the second term. The first three terms are, in order, x−d,x,x+d.The sum of the first three terms is (x−d)+x+(x+d)=111.

Correct answer:31Explanation:Let d be the common difference, and let x be the second term. The first three terms are, in order, x−d,x,x+d.The sum of the first three terms is (x−d)+x+(x+d)=111.x+x+x+d−d=3x=111

Correct answer:31Explanation:Let d be the common difference, and let x be the second term. The first three terms are, in order, x−d,x,x+d.The sum of the first three terms is (x−d)+x+(x+d)=111.x+x+x+d−d=3x=111x=1113=37

Correct answer:31Explanation:Let d be the common difference, and let x be the second term. The first three terms are, in order, x−d,x,x+d.The sum of the first three terms is (x−d)+x+(x+d)=111.x+x+x+d−d=3x=111x=1113=37Now we know that the second term is 37. The fourth term is the second term plus twice the common difference: x+2d. Since the second and fourth terms are 37 and 49, respectively, we can solve for the common difference.
