Q
Q: In a sequence defined by a_n = n^2 + n, what is the value of a_5? (2023)
Solution:
Substituting n = 5 gives a_5 = 5^2 + 5 = 25 + 5 = 30.
Steps: 6
Show Steps
Step 1: Identify the formula for the sequence, which is a_n = n^2 + n.
Step 2: Determine the value of n we want to use. In this case, n = 5.
Step 3: Substitute n = 5 into the formula: a_5 = 5^2 + 5.
Step 4: Calculate 5^2, which is 25.
Step 5: Add 5 to 25: 25 + 5 = 30.
Step 6: Conclude that the value of a_5 is 30.
