2F3, 3O5, 5I7, 7Y11, ____a)11L13b)11J15c)13M17d)11M13Correct answer is...
- In each term the numbers are pairs of consecutive prime numbers.
- The letter between them has the place value equal to the product of the two numbers on either side of it.
∵ The next two prime numbers are 11 and 13 whose product is 143. The 143rd letter is (26 × 5 + 13) M.
as there are only 26 alphabet so there would be multiple rounds to reach 143 and we have to look at remainder.
∴ 11M13 is the next term.

The given sequence is: 2F3, 3O5, 5I7, 7Y11.
- The numbers in the sequence follow a pattern where the odd-positioned elements are increasing by 2, and the even-positioned elements are increasing by 4.
- The odd-positioned elements are obtained by adding 2 to the previous odd-positioned element.
- The even-positioned elements are obtained by adding 4 to the previous even-positioned element.
- The letters in the sequence also follow a pattern where they alternate between consonants and vowels.
- The consonants are obtained by adding the position number of the previous element in the sequence to the previous consonant.
- The vowels are obtained by adding the position number of the previous element in the sequence to the previous vowel.
To find the missing element in the sequence, we need to continue the pattern:
1. The missing element is at the 5th position in the sequence, so it will be an odd-positioned element.
2. The previous odd-positioned element is 7Y11.
3. To find the next odd-positioned element, we add 2 to the last number, which gives us 11.
4. Therefore, the missing element is 11.
Next, let's determine the consonant and vowel for the missing element:
1. The missing element is at the 5th position in the sequence, so it will be a consonant.
2. The previous consonant is I.
3. To find the next consonant, we add the position number (5) to the previous consonant.
4. The position number is represented by the alphabet E, so adding E to I gives us M.
5. Therefore, the missing consonant is M.
Combining the missing odd-positioned element and consonant, we get 11M.
Finally, let's determine the vowel for the missing element:
1. The missing element is at the 5th position in the sequence, so it will be a vowel.
2. The previous vowel is 7.
3. To find the next vowel, we add the position number (5) to the previous vowel.
4. The position number is represented by the alphabet E, so adding E to 7 gives us 13.
5. Therefore, the missing vowel is 13.
Combining the missing odd-positioned element, consonant, and vowel, we get 11M13.
Therefore, the missing element in the sequence is 11M13, which corresponds to option D.
- The numbers in the sequence follow a pattern where the odd-positioned elements are increasing by 2, and the even-positioned elements are increasing by 4.
- The odd-positioned elements are obtained by adding 2 to the previous odd-positioned element.
- The even-positioned elements are obtained by adding 4 to the previous even-positioned element.
- The letters in the sequence also follow a pattern where they alternate between consonants and vowels.
- The consonants are obtained by adding the position number of the previous element in the sequence to the previous consonant.
- The vowels are obtained by adding the position number of the previous element in the sequence to the previous vowel.
To find the missing element in the sequence, we need to continue the pattern:
1. The missing element is at the 5th position in the sequence, so it will be an odd-positioned element.
2. The previous odd-positioned element is 7Y11.
3. To find the next odd-positioned element, we add 2 to the last number, which gives us 11.
4. Therefore, the missing element is 11.
Next, let's determine the consonant and vowel for the missing element:
1. The missing element is at the 5th position in the sequence, so it will be a consonant.
2. The previous consonant is I.
3. To find the next consonant, we add the position number (5) to the previous consonant.
4. The position number is represented by the alphabet E, so adding E to I gives us M.
5. Therefore, the missing consonant is M.
Combining the missing odd-positioned element and consonant, we get 11M.
Finally, let's determine the vowel for the missing element:
1. The missing element is at the 5th position in the sequence, so it will be a vowel.
2. The previous vowel is 7.
3. To find the next vowel, we add the position number (5) to the previous vowel.
4. The position number is represented by the alphabet E, so adding E to 7 gives us 13.
5. Therefore, the missing vowel is 13.
Combining the missing odd-positioned element, consonant, and vowel, we get 11M13.
Therefore, the missing element in the sequence is 11M13, which corresponds to option D.
