thnku...Hope it helps uhh.
Therefore the complete series is 100, 95, 88, 79, 68, 55, 40, 23.
Given:
The series: 100,95, ?, 79,68,?,40,23
To Find:
The missing terms in the given series.
Solution:
The given question can be solved very easily as shown below.
Given series: 100,95, x, 79,68,y,40,23
⇒ The second term '95' can be written from '100-5'.
The third term can be formed by subtracting the next odd number after '5' from '95'
⇒ The third term 'x' can be written from '95-7'.
So x = third term = second term - 7 ( Odd number after 5 ) = 95-7 = 88
⇒ The fourth term '79' can be written from '88-9'. Where 9 is the next odd number after 7.
⇒ The fifth term '68' can be written from '79-11'. Where 11 is the next odd number after 9.
⇒ Similarly sixth term = fifth term - 13 ( odd number after 11 )
⇒ y = sixth term = 68-13 = 55
Hence the series is 100,95, 88, 79,68,55,40,23
Therefore the complete series is 100, 95, 88, 79, 68, 55, 40, 23.
