If 1+1=5, 2+2=20, 3+3=45, 5+5=125,Then 8+8=?   Answer If 1+1=5, 2+2=18, 3+3=39, 4+4=68, then what is the value of 8+8? 8+8=264 Proof: 1+1=5 i.e,1+1+1+1+1=5. 5 times add 1 2+2=18 i.e,2+2+2+2+2+2+2+2+2=18 9 times add 2 i.e,the times of adding a number is incremented by four. 3+3=39 i.e,3+3+3+3+3+3+3+3+3+3+3+3+3=39 13 times add 3 Similarly,the times of adding a number is incremented by four. 4+4=68 i.e,4+4+4+4+4+4+4+4+4+4+4+4+4+4+4+4+4=68 17 times add 4 Similarly,the times of adding a number is incremented by four. Similarly,for 8+8=264 33 times 8 get added by 8 following the above series U can watch more videos on to my channels And don't forget to LIKE  SHARE SUBSCRIBE COMMENT  Facebook https://youtube.com/@MathsTheoryy Moj https://sharechat.com/profile/mathstheory?d=n
