y=4

2x + 1 = 13; 2x = 12; x = 6

9 plus 135 = 16 The series is formed by dividing the second number by the first number and then adding 1 to the quotient. 18 ÷ 3 = 6 : 6 + 1 = 7 14 ÷ 7 + 2 : 2 + 1 = 3 18 ÷ 6 = 3 : 3 + 1 = 4 112 ÷ 8 = 14 : 14 + 1 = 15 135 ÷ 9 = 15 : 15 + 1 = 16

yes! 11+2=13 12+1=13
