Question

If 11, x, are the terms of an A.P, Then value of x will be​

Answer 1

The value of x is equal to 8.
Step-by-step explanation:
Given,
11, x, 5 are the terms of an AP.
Here, first term = 11, second term = x and third term = 5
To find, the value of x = ?
We know that,
Common difference (d) = Second term - First term = Third term - Second term
⇒ x - 11 = 5 - x
⇒ x + x = 5 + 11
⇒2x = 16
⇒ x = = 8
∴ x = 8
Thus, the value of x is equal to 8.

Answer 2

we need at least 3 terms to find x

to find x we should know 'd'

we can't find d from 1 term...
