Question

Help me out
Give the correct answer
1+2=21
2+3=36
3+4=43
4+5=?​

Answer 1

1 + 2 = 21 (reversing numbers)

2 + 3 = 32 (reversing numbers) + 4 = 36

3 + 4 = 43 (reversing numbers)

4 + 5 = 54 (reversing numbers) + 4 =58

Answer 2

58

Explanation:

This is a sequence using reversed numbers, and alternating a summing fixed amount.

In the first one you can see that it's only numbers being reversed.

The second one is also reversing numbers but adding 4 units, 32+4=36.

The third one has the same pattern in the first one, just numbers being reversed.

The fourth has the same pattern than the second one, reversed numbers and add 4 units. So, it would be 54+4=58.

Therefore, the answer is 58.
