39

Answer 2

The 10th term of the AP is 39

Given :

1st term and the common difference of an AP are 3 and 4 respectively

To find :

The 10th term of the AP

Solution :

Concept :

If in an arithmetic progression

First term = a

Common difference = d

Then nth term of the AP

= a + ( n - 1 )d

Solution :

Step 1 of 2 :

Write down first term and common difference

First term = a = 3

Common Difference = d = 4

Step 2 of 2 :

Find the 10th term of the AP

Then 10th term of the AP

= a + ( 10 - 1 )d

= a + 9d

= 3 + ( 4 × 9 )

= 3 + 36

= 39
