Question

6. 10th term of the AP: 10, 7, 4.​

Answer 1

Answer:

Step-by-step explanation:

here a = 10

d = t2-t1 = 7-10 = -3

n = 10

An = a+(n-1)d

    = 10+(10-1)(-3)

    = 10 +9(-3)

    = 10-27

     = -17

hence 10nth term of the given AP is -17

Answer 2

Answer:

AP-10,7,4......

So:-

• A1=10
• A2=7
• A3=4

Common difference=A2-A1

Common difference=7-10=-3

We have to find 10th term so n =10

Now applying formula

An=A1+(n-1)D

A10=10+(10-1)(-3)

A10=10+9(-3)

A10=1-27

A10=-26
