Answer 1

Answer:

=7+17/2

=24/2

=12

______

Answer 2

Solution:

Given:

• 7, x and 17 are in A.P.

To Find:

• The value of x.

A.P. stands for Arithmetic Progression. In this sequence, the difference between each term remains same, also known as common difference.

Here, we have to find out x.

So, according to the condition,

→ x - 7 = 17 - x

→ x + x = 17 + 7

→ 2x = 24

→ x = 24/2

→ x = 12

★ So, the value of x is 12.

Answer:

• x = 12.

Verification:

To verify our result, we have to check whether the common difference is same everywhere.

→ x - 7 = 12 - 7 = 5

→ 17 - x = 17 - 12 = 5

So, common difference is same everywhere. Therefore, our answer is correct (Verified)
