Question

Solve.
36+96-72+67÷45×7-21=?

solve the problem ​

Answer 1

Answer:

It’s amazing to see that there are so many different logics arriving at the same answer 98!

When I first saw the question, I deduced the answer by logic:

X1 + X2 = X1( X2 +k), where k is the term of A.P : 1,2,3,4,5…( or the sequence no. of question)

2+3= 2(3+1)= 8

3+7= 3(7+2)=27

4+5=4(5+3)=32

5+8=5(8+4)= 60

6+7=6(7+5)= 72

And thus:

6. 7+8=7(8+6)= 98
