Question

find the 19th term of the following A.P. 7,13,19,25​

Answer 1

Step-by-step explanation:

first term(a)=7 , comman difference (d)=13-7=6

T(n)=a+(n-1)d

T(19)=7+(19-1)6

=7+18*6

=7+108

=115.

so the 19th term of AP is 115

Answer 2

Answer:

Here, Our 19th term is 115.

Step-by-step explanation:

Here, As given our question,

=First term(a)=7

=Common difference(d)=13-7=6

Our term is=19

Now, =Tn=a+(n-1)×d

=T19=a+(n-1)×d

=7+(19-1)×6

=7+18×6

=7+108

=115

So, our 19th term in this AP =115 (Answer)

Thank you.
