Question

1+2=21
2+3=36
3+4 =43
4+5=??

Answer 1

4 + 5 = 58

Explanation:

• Missing number is a type of logical reasoning where a particular mathematical pattern is followed. The pattern needs to be identified and missing number is calculated.
• Here, first three equations are solved and we need to infer the pattern from these three equation.
• It can be seen that in first and third equation numbers are reversed. In 1 + 2 = 21, second number takes the tens position in the number (2) and first number takes the ones position (1)
• Similarly in 3 + 4 = 43, 4 takes tens and 3 takes ones position to form the number 43.
• in the second equation, numbers are reversed and 4 is added to the final number. 2 + 3 is written as 32 and 4 is added to this number to get 36
• Similarly, in the last equation, 4 + 5 is written as 54 and 4 is added to this number to obtain 58,

So following is the pattern:

1 + 2 = 21 + 0 = 21

2 + 3 = 32 + 4 = 36

3 + 4 = 43 + 0 = 43

4 + 5 = 54 + 4 = 58
