Find the 19th term of the following AP,
7,13,19,25......
Answer: 115
The given sequence is 7, 13, 19, 25, ....
Here,
First term = a = t1 = 7, t2 = 13, t3 = 19, t4 = 25, ....
Common difference = d = t2 - t1
= 13 -7
= 6
To find the 19th term, we have to use the formula, i.e.,
tn = a + (n - 1)d
t19 = 7 + (19 - 1) Ć 6 ...(On substituting value)
=7+ 18 Ć 6
= 7 + 108
= 115
Therefore the 19th term of the progression is 115.
