Question

Найди лишнее число и объясни почему оно лишнее- 13,22,39,64,76

Answer 1

Лишнее - число 13, потому что оно простое (имеет только два множителя: единицу и само число)
22 = 2 * 11 
39 = 3 * 13 
64 = 2 * 2 * 2 * 2 * 2 * 2
76 = 2 * 2 * 19

Answer 2

Finding the Odd Number in the Sequence

To find the odd number in the sequence 13, 22, 39, 64, 76, we need to examine each number and determine which one does not fit the pattern.

Let's analyze each number in the sequence:

- 13: This is an odd number. - 22: This is an even number. - 39: This is an odd number. - 64: This is an even number. - 76: This is an even number.

From the given sequence, we can see that all the numbers except 22 are either odd or even. Therefore, 22 is the odd number in the sequence.

Please note that the explanation provided above is based on the analysis of the given numbers and does not rely on external sources.
