Question

What will come in place of the question mark (?) in the following
number series?
? , 98, 291, 1160, 5795

Answer 1

Given series is :

? , 98 , 291 , 1160 , 5795

Solution :

we can see in the series

that

● 291 = 98 × 3 - 3

● 1160 = 291 × 4 - 4

● 5795 = 1160 × 5 - 5

then,

Let the missing term be ' m '

➹ 98 = m × 2 - 2

➹ 98 = 2 m - 2

➹ 98 + 2 = 2 m

➹ 100 = 2 m

➹ m = 50

Hence,

The missing term will be 50 .
