Question

Find the 7 th term of ap 24, 21, 18​

Answer 1

Answer:

The 7th term is 6

Step-by-step explanation:

24, 21, 18​

Every sequences is -3

7-3=4

-3*4= -12

The 7th term will be 18-12

=6

Answer 2

Answer:

Step-by-step explanation:

In the given AP, a=t1=24, t2=21, t3=18, d=t2-t1=21-24=-3.

7th term of AP=t7=a+(n-1)d.

Therefore,t7=24+(7-1)-3.

Therefore,t7=24+(-21+3)

Therefore,t7=24+(-18)

Therefore,t7=24-18

Therefore,t7=6.

Thus,7th term of given AP is 6.
