GIVEN

A positive decrementing series

109,102,95,__,81.

FIND

The missing number between 95 and 81.

SOLUTION

• To solve such questions we must find the hidden relation between the terms of the series.

• The relation generally lies between the sum , difference or product of the terms.

• For this series, by observation we can conclude that there is difference of 7 between the alternate terms. i.e. 109-102=7,102-95=7,etc.

• Hence the missing number is 7 less than preceding number i.e. 95 so, 95-7 = 88 .

The missing number in the series is 88.
