Question

if ap:3,5,7...find 10th term ​

Answer 1

Answer:

here is the answer

Step-by-step explanation:

a=3

a2=5

which means a+d=5

so,3+d=5

d=2

this,a10=a+9d=3+9(2)=3+18=21

Answer 2

Answer:

The 10th term of the AP = 21

Step-by-step explanation:

Given AP is :3,5,7...

To find,

10th term of the AP

Recall the formula

The nth term of an AP = a+(n-1)d, where 'a' is the first term and 'd' is the common difference of the AP

Solution:

Given AP is 3,5,7,......

First term of the AP = a = 3

The common difference of the AP = d = 5-3 = 2

Since nth term of the AP = a+(n-1)d,

the 10th term = a+(10-1)d

= 3+9×2

= 3+18

= 21

∴The 10th term of the AP = 21
