Question
The average of series 'S2', which consists of 6 consecutive
even numbers, is 29. The second term of series 'T2', which consists of 5 consecutive odd numbers, is 5 more than the first term of series 'S2'. Find the average of series 'T2'.Solution
Let six consecutive even numbers be 'a', (a + 2), (a + 4), (a + 6), (a + 8) and (a + 10), respectively.
ATQ,
a + a + 2 + a + 4 + a + 6 + a + 8 + a + 10 = 29 X 6
Or, 6a = 174 - 30
So, 'a' = (144 / 6) = 24
So, 2nd term of series 'T2' = 24 + 5 = 29
So, series 'T2' = 27, 29, 31, 33, 35
Therefore, required average = (27 + 29 + 31 + 33 + 35) ÷ 5 = 31
