Question

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

Answer 1

Hey !!!

a (first term ) = 7

d (common difference) = t2 -t1 = 13-7 = 6

n = 19

tn = a + ( n - 1 ) d

t19 = 7 + ( 19 - 1 ) 6

t19 = 7 + 108

t19 = 115 Answer

Answer 2

Answer:

115

Step-by-step explanation:

A. P. - 7, 13, 19, 25,...

Common difference = d = 13-7=19-13 =6

$a_1 = 7$

Formula of nth term= $a_n=a+(n-1)d$

$a_{19}=7+(19-1)6$

$a_{19}=115$

Hence the 19th term is 115
