प्रश्न
Fill in the blank in the following table, given that a is the first term, d the common difference, and an nth term of the AP:
a | d | n | an |
3.5 | 0 | 105 | ______ |
उत्तर
a | d | n | an |
3.5 | 0 | 105 | 3.5 |
Explanation:
a = 3.5, d = 0, n = 105, an = ?
We know that,
an = a + (n - 1) d
an = 3.5 + (105 - 1) 0
an = 3.5 + 104 × 0
an = 3.5
Hence, an = 3.5
