Question

198,194,185,169,? what will be the next number?

Answer 1

198, 194 , 185 , 169
198 - (2)² = 198 - 4 =194
194 - (3)² =  194 - 9 =185
185 - (4)² =  185 - 16 = 169
169 - (5)² =  169 - 25 = 144

Answer 2

Answer : Next number will be 144

Step-by-step explanation:

Given :

198,194,185,169, ?

First, Find out how the sequence is formed :-

$198 - {2}^{2} = 198 - 4 = 194$

$194 - {3}^{2} = 194 - 9 = 185$

$185 - {4}^{2} = 185 - 16 = 169$

$169 - {5}^{2} = 169 - 25 = 144$

So, By observing we know that the natural number squares are subtracted from the before terms.

Hence, Required answer is 144
