Correct Answer - Option 3 : 70

The logic followed is:

Given arithmetic progressive series: 6, 10, 14, _ _ _ _ _

we can see a common difference = 4

First-term = 6

To find **nth term of an AP is, Tn = a + (n - 1)d**

Thus 17^{th} term in this series ⇒ T_{17} = 6 + (17 - 1)4

**T**_{17} = 6 + (16)4

**T**_{17} = 6 + 64

**T**_{17} = 70

Hence, the correct answer is** "70".**
