because it is arithmetic not geometric 14,x,56 An = An-1 + d x = 14 +d --> d = x-14 56 = x +d --> d = 56-x By substitution x-14 = 56-x 2x = 70 x = 35 the sequence is 14,35,56

-5

Step-by-step explanation:

x + x² = 20

x² + x - 20 = 0

Factor

(x + 5)(x - 4) = 0

x = {-5, 4}

-5 + 25 = 20

4 + 16 = 20
