Question

x - 2/5 is a even number. What will be the 15 th odd number after it.

Answer 1

The first odd number after is
$x - \frac{2}{5} + 1 = x + \frac{3}{5}$
For the next odd numbers we keep adding 2.
This implies we can form an Arithmetic Progression from it whose
$first \: term = x + \frac{3}{5} \: and \\ common \: difference = 2$
Therefore, 15th odd number should be the 15th term of the AP which is
$first \: term + (15 - 1) \times 2 \\ = x + \frac{3}{5} + 14 \times 2 \\ = x + \frac{3}{5} + 28 \\ = x + \frac{143}{5}$

Answer 2

Answer:

Step-by-step explanation:

The next odd no. After x-2/5 is x-2/5+1

I.e. x-2+5/5

=x+3/5

Now,14th odd number after x+3/5

The required number is

x+3/5+2×14

=X+3/5+28

=X+3+140/5

=X+143/5
