solve if u can
1+2-3 = 5
2+3-4 = 10
3+4-5 = 17
4+5-6 = ??

1+2-3=5
2+3-4=10
3+4-5=17
4+5-6=26
Because:
-In the first line the answer is 5 because 2+3=5 in the same way In the second line the answer is 10 because 2+3+5=10 in the same way In the third line the answer is 17 because 3+4+10=17 in the same way In the fourth line the answer will be 26 because 4+5+17=26.
