The given series is in the below pattern,
First term = 10
Second term = First term + 5 = 15
⇒ Second term = 10 + 5 =15 ,
Third term = Second term + 9 = 24
⇒ Third term = 15 + 9 = 24 ,
Similarly , we can find the all others terms also.
24 + 13 = 35, is wrong. It should be 37.
Fourth term = Third term + 13 = 37 + 17 = 54 ,
Fifth term = Fourth term + 17 = 54 + 21 = 75 ,
Sixth term = Fifth term + 21 = 75 + 25 = 100
The difference in successive nos. 9 – 5 = 13 – 9 = 17 – 13 = 21 - 17 = 4.
Hence, 35 is wrong. It should be 37.
