An arithmetic problem 7.7.9.17.34. () what to fill in the brackets? Give the algorithm, 7 + 7-5 = 9; 7 + 7 + 9-6 = 17; 7 + 7 + 9 + 17-7 = 33; it's not 34; so Add the first two - 5 Add the first three - 6 Add the first four - 7 and 7.7.9.17.34. () what do you fill in the brackets? 7+7-5=9 9+17-9=17 17+34-13=38 Can the algorithm have a better basis? Which function is 5 9 13 each time + 4. Isn't it a bit far fetched That's it. Fill in the last number The final answer is 43. I hope you can think about the algorithm

7.7.9.17.34. () what do you fill in the brackets?
7+7-5=9
9+17-9=17
17+34-13=38
My guess is 38
