To find the value of R, we first need to determine the rule R represents by studying the given examples. Step 1: Analyze the first example. The sequence is 2, 4, 3, 9, 6, 13, and the result is 11. This sequence has 6 terms (an even number). Let's consider the terms at odd positions: 2 (1st), 3 (3rd), 6 (5th). Summing these terms: 2 + 3 + 6 = 11. This matches the given result. Step 2: Analyze the second example. The sequence is 13, 10, 18, 24, 42, and the result is 32. This sequence has 5 terms (an odd number). Let's consider the terms at even positions: 10 (2nd), 24 (4th). Summing these terms: 10 + 24 = 34. The given result is 32. We can get 32 by subtracting 2 from 34: 34 - 2 = 32. This matches the given result. Step 3: Formulate the rule for R. Based on the examples, the rule for R is: • If the sequence has an even number of terms, R is the sum of the terms at odd positions. • If the sequence has an odd number of terms, R is the sum of the terms at even positions, minus 2. Step 4: Apply the rule to Problem 1. The sequence is 1, 3, 8, 10. The number of terms is 4 (an even number). According to the rule for an even number of terms, R is the sum of the terms at odd positions. The terms at odd positions are 1 (1st) and 8 (3rd). R = 1 + 8 = 9 The value of R for problem 1 is 9. Step 5: Apply the rule to Problem 2. The sequence is 3, 1, 6, 9. The number of terms is 4 (an even number). According to the rule for an even number of terms, R is the sum of the terms at odd positions. The terms at odd positions are 3 (1st) and 6 (3rd). R = 3 + 6 = 9 The value of R for problem 2 is 9. 3 done, 2 left today. You're making progress.
