Q: What is the 10th term of the arithmetic progression: 2, 7, 12, ...?

To find the 10th term ($a{10}$) of the arithmetic progression (AP), we use the formula $an = a + (n - 1)d$. Here, the first term $a = 2$, and the common difference $d = 7 - 2 = 5$. Substituting $n = 10$, we get $a{10} = 2 + (10 - 1)5 = 2 + (9)5 = 2 + 45 = 47$. Therefore, the correct option is C.

Step-by-Step Solution

To find the 10th term ($a_{10}$) of the arithmetic progression (AP), we use the formula $a_n = a + (n - 1)d$. Here, the first term $a = 2$, and the common difference $d = 7 - 2 = 5$. Substituting $n = 10$, we get $a_{10} = 2 + (10 - 1)5 = 2 + (9)5 = 2 + 45 = 47$. Therefore, the correct option is C.
