What is the 15th term of an arithmetic progression where the first term is 7 and the common difference is 2? (2023)

What is the 15th term of an arithmetic progression where the first term is 7 and the common difference is 2? (2023)

Step 1: Identify the first term of the arithmetic progression, which is given as 7.
Step 2: Identify the common difference, which is given as 2.
Step 3: Determine which term we want to find. In this case, we want the 15th term.
Step 4: Use the formula for the nth term of an arithmetic progression: nth term = first term + (n - 1) * common difference.
Step 5: Substitute the values into the formula: 15th term = 7 + (15 - 1) * 2.
Step 6: Calculate (15 - 1) which equals 14.
Step 7: Multiply 14 by the common difference (2): 14 * 2 = 28.
Step 8: Add this result to the first term: 7 + 28 = 35.
Step 9: Conclude that the 15th term of the arithmetic progression is 35.
