Correct Marty.

 

10 = 25   >    2 x 10 + 5  =  25

15 = 50   >    3 x 15 + 5  =  50

20 = 85  >    4 x 20 + 5  =  85,     therefore

25 = ?     >    5 x 25 + 5  =  130.

DR.

Interesting with the previous one, I didn't do the multiplication method, I thought it was the sum of the previous numbers.

(10+15+25 =50, 15+50+20=85, so 20+85+25=130)
