Question

If an A.P . 17th term is 7 more than its 10tg term. Find the common difference. ​

Answer 1

Answer:

let the 17th term be t17

therefore t17= a+ (17-1) d

a+16d

t10= a+ (10-1) d

a+9d

by given condition

t17=7+ t10

a+16d=7+ a+ 9d

a and -a get cancelled

so,

16d=7+9d

16d-9d=7

7d=7

therefore d=1
