Question

Find the ${10}^{th}$ term of the AP : 2, 7, 12, . . .

• A. 57
• B. 52
• C. 47
• D. 42

Answer 1

The correct option is C

47

Here, a = 2, d = 7 – 2 = 5 and n = 10.

We have $a_n$ = a + (n – 1) d

So, $a_{10}$ = 2 + (10 – 1) $\times$ 5 = 2 + 45 = 47

Therefore, the ${10}^{th}$ term of the given AP is 47.
