Solution

The correct option is A
2n+3

Since, the difference between the two consicutive terms is 1 ${2 n - (2 n - 1) = 1}$

So, the next term = 2n+2+1

= 2n+3

The next number in the series is ___ ? 2n-1,2n,2n+1, 2n+2,___

The correct option is A 2n+3 Since, the difference between the two consicutive terms is 1 {2n−(2n−1)=1} So, the next term = 2n+2+1 = 2n+3

The next number in the series is _ ?

2n-1,2n,2n+1, 2n+2,_

The correct option is A
2n+3

Since, the difference between the two consicutive terms is 1 ${2 n - (2 n - 1) = 1}$

So, the next term = 2n+2+1

= 2n+3
