Answer 2

The pattern in the given sequence appears to involve a relationship between numbers and letters. Let's try to decipher it:

• 15a : 3
• 216 : 7
• 42c : 6

It seems like there might be a relationship between the first number and the letter, as well as a relationship between the second number and the sequence in which the letter appears in the English alphabet.

Here's a possible pattern:

1. The first number represents the sum of the digits in the number.

   • For 15a, 1 + 5 = 6
   • For 216, 2 + 1 + 6 = 9
   • For 42c, 4 + 2 = 6

2. The second number corresponds to the position of the letter in the English alphabet.

   • For 'a,' which is the 1st letter, the number is 1.
   • For 'c,' which is the 3rd letter, the number is 3.

Now, let's test this pattern:

• For 15a: (1 + 5) = 6, and 'a' is the 1st letter, so 15a : 6, which matches the pattern.

• For 216: (2 + 1 + 6) = 9, and '6' is the 9th letter in the alphabet (focusing on the letters in "six"), so 216 : 9, which also matches the pattern.

• For 42c: (4 + 2) = 6, and 'c' is the 3rd letter, so 42c : 6, which again matches the pattern.

So, based on this pattern, the correct answer for the sequence "15a : 3; 216 : 7; 42c : 6" would be "15a : 6."
