What will be the 10th term in the given sequence?3, 7, 11, 15, 19, 23
Correct answer: C. 39
- A. 27
- B. 35
- C. 39
- D. 43
Explanation
The given sequence is an arithmetic progression (AP) with the first term a = 3 and a common difference d = 4. The formula for the nth term of an AP is given by an = a + (n-1)d. To find the 10th term:a10 = 3 + (10-1) * 4 = 3 + 36 = 39Therefore, the 10th term is 39.The other options are incorrect because they either do not follow the arithmetic progression or represent terms other than the 10th, as explained in their respective explanations.
