Substituting n = 6 into the formula: a_6 = 6^2 + 2(6) = 36 + 12 = 48.
Steps: 7
Show Steps
Step 1: Identify the formula for the nth term, which is n^2 + 2n.
Step 2: Determine the value of n for the 6th term, which is n = 6.
Step 3: Substitute n = 6 into the formula: a_6 = 6^2 + 2(6).
Step 4: Calculate 6^2, which is 36.
Step 5: Calculate 2(6), which is 12.
Step 6: Add the results from Step 4 and Step 5: 36 + 12 = 48.
