What is the next number in the series 70, 54, 45, 41, ?

Answer»

Answer:

40

Step-by-step explanation:

Given terms are getting decreased by the square of numbers from 4 in decreasing order. To clear more:

First number is 70, to get the second number it is decreased by the square of 4 i.e. 16.

 that's how second TERM is 70 - 4^2 = 70 - 16 = 54

And similarly:

 Third term = 54 - 3^2 = 54 - 9 = 45

Fourth term = 45 - 2^2 = 45 - 4 = 41

Hence,

Fifth term = 41 - 1^2 = 41 - 1 = 40
