For the sequence provided below, determine the incorrect term:

2, 4, 7, 13, 19, 30, 43

The correct answer is 13.

Step-by-Step Explanation:

Let us analyze the given sequence to find the underlying pattern:

2, 4, 7, 13, 19, 30, 43

First, we calculate the differences between consecutive terms in the sequence:

4 - 2 = 2

7 - 4 = 3

19 - 13 = 6 (if using 13)

30 - 19 = 11

43 - 30 = 13

Let us look at the sequence of differences between terms:

If we examine prime numbers starting from 2:

The sequence of prime numbers is: 2, 3, 5, 7, 11, 13, ...

Let us apply these prime number differences starting from the first term, 2:

First term: 2

Second term: 2 + 2 = 4

Third term: 4 + 3 = 7

Fourth term: 7 + 5 = 12 (instead of 13)

Fifth term: 12 + 7 = 19

Sixth term: 19 + 11 = 30

Seventh term: 30 + 13 = 43

As we can see, adding consecutive prime numbers (2, 3, 5, 7, 11, 13) yields the exact terms of the given sequence, except for the term 13, which should be 12.

Therefore, the incorrect term in the sequence is 13.
