What is the 10th term of the arithmetic progression (A.P.) 2, 7, 12, ...?

Question

Accepted Answer

To find the 10th term of the A.P., we use the formula $an = a + (n - 1)d$. Here, the first term $a = 2$, the common difference $d = 7 - 2 = 5$, and the number of terms $n = 10$. Substituting these values into the formula: $a{10} = 2 + (10 - 1) 	imes 5 = 2 + 9 	imes 5 = 2 + 45 = 47$. Therefore, the correct option is C.
