WebExample 2: How many three-digit numbers are divisible by 3? Solution: The smallest three-digit number which is divisible by 3 is 102 and the largest three-digit number divisible by 3 is 999.To find the number of terms in the following AP: 102, 105, 108,..,999, we will take 999 be the n th term of AP, it can be seen that a is equal to 102, and d is equal to 3. WebDec 28, 2024 · a = a₁ + (n-1)d. where: a — The nᵗʰ term of the sequence; d — Common difference; and. a₁ — First term of the sequence. This arithmetic sequence formula applies in the case of all common differences, whether positive, negative, or equal to zero. Naturally, in the case of a zero difference, all terms are equal to each other, making ...

So the formula a (n) = S (n) -S (n-1) works only for n > 1.
