Question

1 2 = 21 2 3 =36 3 4 = 43 4 5 =?
No es 58

Answer 1

4 + 5 = 54 + 4 = 58 is missing number in the series.

Step-by-step explanation:

There are four sequences in given series:

1 + 2 = 21 + 0 = 21

Reverse the number 12 and add 0 to it  = 21 + 0 =21

2 + 3 = 32 + 4 = 36

Reverse the number 23 and add 4 to it  = 32 + 4 =36

3 + 4 = 43 + 0 = 43

Reverse the number 34 and add 0 to it = 43 + 0 =43

4 + 5 = 54 + 4

Reverse the number 45 and add 4 to it  = 54 + 4 =58

Thus, next number in the series is 58

Answer 2

Answer:

1 2 = 21 2 3 =36 3 4 = 43 4 5 =58

Step-by-step explanation:

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

1 2 = 21 + 0 = 21 (Reverse the number 12 and add 0 to it  = 21 + 0 =21)

2 3 = 32 + 4 = 36 (Reverse the number 23 and add 4 to it  = 32 + 4 =36)

Similarly,

3 + 4 = 43 + 0 = 43 (Reverse the number 34 and add 0 to it = 43 + 0 =43)

4 + 5 = 54 + 4=58 (Reverse the number 45 and add 4 to it  = 54 + 4 =58)

Thus, next number in the series is 58
