Question

Find the 10th term of an A. P. if a = 7 , d = 4​

Answer 1

Answer:

a10=a+9d

Step-by-step explanation:

a=7

d=4

so,

a10=a+9d=7+9*4

     =7+36

     =43

Answer 2

Answer :

a = 7

d = 4

a10 = a + 9d

= 7 + 9*( 4 )

= 7 + 36

= 43

Other methods :

10th term = a + 9d

10th term = a + 9d

10th term = 7 + 9* (- 4 )

==> 7 + ( - 36 )

==> - 29
