Question

If Arithmatic Mean of 5 consecutive odd number is 63 then the fourth number in the series is

Answer 1

Answer:

65

Step-by-step explanation:

Since it is given as consecutive odd numbers, let us take,

( X + (X+2) + (X+4) + (X+6) + (X+8) ) / 5 = 63

X + (X+2) + (X+4) + (X+6) + (X+8) = 63×5 = 315

5X + 20 = 315

5X = 315 - 20

5X = 295

X = 295 ÷ 5

X = 59.

Now, the series becomes, 59, 61, 63, 65, 67.

The fourth number in the series is 65.
