Using the examples provided, determine the operation R for the given sequences.

The problem asks us to find the value of R for the given sequences by studying the provided examples. R represents a specific operation applied to the sequence to get the final number.

Let's analyze the examples to determine the rule for R.

• Example 1: Sequence: $2, 4, 3, 9, 6, 13$ Result: 11

  Let's separate the numbers into two interleaved sequences:

  • Numbers at odd positions (1st, 3rd, 5th): $2, 3, 6$
  • Numbers at even positions (2nd, 4th, 6th): $4, 9, 13$

  If we
