Answer 2

Finding the 12th Term of an Arithmetic Progression

To find the 12th term of the given arithmetic progression, we can use the formula for the nth term of an arithmetic progression:

nth term (Tn) = a + (n - 1)d

Where: - a = the first term of the arithmetic progression - n = the term number - d = the common difference between terms

Applying the Formula

Given the sequence 7, 12, 17, ..., we can identify: - The first term (a) = 7 - The common difference (d) = 12 - 7 = 5

Now, we can use the formula to find the 12th term: T12 = 7 + (12 - 1) * 5

Calculation

T12 = 7 + 11 * 5 T12 = 7 + 55 T12 = 62

Therefore, the 12th term of the given arithmetic progression is 62. This calculation is based on the provided arithmetic sequence and the formula for the nth term of an arithmetic progression.
