Q
Q: If a sequence is defined as a_n = 3n + 2, what is a_4?
Solution:
a_4 = 3(4) + 2 = 12 + 2 = 14.
Steps: 5
Show Steps
Step 1: Identify the formula for the sequence, which is a_n = 3n + 2.
Step 2: Substitute n with 4 in the formula to find a_4. So, we have a_4 = 3(4) + 2.
Step 3: Calculate 3 times 4, which is 12.
Step 4: Add 2 to the result from Step 3. So, 12 + 2 equals 14.
Step 5: Therefore, a_4 is 14.
