Question

(X-2)÷5 is an even number. What is the 15th odd number after it ?

Answer 1

Answer:

Step-by-step explanation:

Sol:

x - 2/5 is an even number.

⇒ (x - 2/5) + 1 is an odd number.

[Odd and even numbers are consecutive.]

15 the odd number after [(x - 2/5) + 1] + (2 x 14)

= [x + 3/5 + 28]

= [x + 143/5]

Therefore, 15th odd number after (x - 2/5) is [x + 143/5].
