For an given A.P. a = 3.5, d = 0, n = 101, then tn = ....
पर्याय
0
3.5
103.5
104.5
उत्तर
3.5
Explanation:
a = 3.5, d = 0, tn = t101
tn = a + (n − 1)d
t101 = 3.5 + (101 − 1)0
= 3.5 + 100 (0)
= 3.5 + 0
= 3.5

Find the sum of natural numbers between 1 to 140, which are divisible by 4.
Activity: Natural numbers between 1 to 140 divisible by 4 are, 4, 8, 12, 16,......, 136
Here d = 4, therefore this sequence is an A.P.
a = 4, d = 4, tn = 136, Sn = ?
tn = a + (n – 1)d
`square` = 4 + (n – 1) × 4
`square` = (n – 1) × 4
n = `square`
Now,
Sn = `"n"/2["a" + "t"_"n"]`
Sn = 17 × `square`
Sn = `square`
Therefore, the sum of natural numbers between 1 to 140, which are divisible by 4 is `square`.
