2*3=15,. 2*5=20,. 2*7=30,. I hope it

(2*3)+9=15,. First question num to add to num 9

(2*5)+10=20 , second question to num add num to 10

(2*7)+16=30 third question num to add num to 16

(2*11)+ 43=65 answer is 65

Why are putting in this numbers you can see for answer is increase that 5 only so that add num is 1,3,5,7,9, so that question second num is get answers is 15 anyway all same method for as .although answer is 15 ,20 ,30 after answer is 65 that is increase of n*2, and n*3 ,etc
