Vedclass · Answer

(B) Let us analyze the pattern of the series:$5 	imes 1.5 = 7.5$$7.5 	imes 1.5 = 11.25$$11.25 	imes 1.5 = 16.875$$16.875 	imes 1.5 = 25.3125$Alternatively,checking the differences:$7.5 - 5 = 2.5$$11.25 - 7.5 = 3.75$$17.5 - 11.25 = 6.25$$29.75 - 17.5 = 12.25$$50 - 29.75 = 20.25$$91.25 - 50 = 41.25$Observing the differences: $2.5, 3.75, 6.25, 12.25, 20.25, 41.25$.The pattern of differences is: $2.5 	imes 1.5 = 3.75$,$3.75 	imes 1.5 = 5.625$ (not $6.25$).If we replace $17.5$ with $16.875$,the series becomes $5, 7.5, 11.25, 16.875, 25.3125, 37.96875, 56.953125$.However,looking at the provided options,$17.5$ is the term that disrupts the geometric progression $a_n = a_{n-1} 	imes 1.5$.

In the following number series,one of the numbers does not fit into the series. Identify the wrong number in the series.
$5 \quad 7.5 \quad 11.25 \quad 17.5 \quad 29.75 \quad 50 \quad 91.25$
