Question

The 7th term of an arithmetic sequence is 17 and 17th term is 7.

a. What is the common difference?

b. Find the 24th term?​

Answer 1

Answer:

0

Step-by-step explanation:

a+6d=17...eqn 1

a+16d=7...eqn 2

subtracting the above eqn we get,

d=-1

substuting d=-1 in eqn 1 we get,

a= 23

so

T24 = a+(n-1) d

T24= 23+(23)-1

T24= 0
