Question

1+2=3 3+4=11 5+6=55 4+5=?

Answer 1

Думаю , здесь используется следующее правило
два последовательных числа складываются, а результат либо умножается на первое, либо к результату прибавляется второе, причём чередование идёт через 2 пары чисел:
1+2=>(1+2)*1=3
2+3=>*
3+4=>(3+4)+4=11
4+5=>+
5+6=>(5+6)*5=55
поэтому
4+5=>(4+5)+5=14

Answer 2

To figure out the pattern in the given equations, let's examine each one:

1 + 2 = 3 3 + 4 = 11 5 + 6 = 55

It seems like the operation being performed between the numbers is not regular addition, but rather some other manipulation. Let's look at the differences between the results of each equation:

3 - 1 = 2 11 - 3 = 8 55 - 5 = 50

The differences between the results are not consistent, which means it's not a straightforward mathematical operation like addition or multiplication.

One possible pattern here could be concatenation (joining numbers together). Let's see if this pattern holds for the next equation:

4 + 5 = 45

Following the pattern, the result of 4 + 5 would be 45.

So, 4 + 5 = 45.
