Question

The fifth and tenth term of an A. P. are 8 and -7 respectively. Find the 100th and 500th terms of the A. P. ​

Answer 1

Answer:

-277, -1477

Step-by-step explanation:

a+4d= 8

a+9d= -7

a+9d-(a+4d)= -7-8

5d=-15

d= -3

a+4d= 8

a- 12=8

a= 20

100th term= a+99d

                 = 20-297

                 = -277

500th term= a+499d

                  = 20- 1497

                  = -1477
