The sum of the series till the 23rd term will be "T₂₃=67". Further explanation is given below.

Step-by-step explanation:

Given series is:

1,4,5,8,9,12....​

According to the series,

The first term, a, a₁=1

The second term, a₂=4

Sum of the series till 23rd term, n=23

The common difference, d=second term-first term

                                          d=a₂-a₁

                                          d=4-1

                                         d=3

Now, Sum of the series, Tn=a+(n-1)d

On putting the values of a, d and n in the above formula, we get

T₂₃=1+(23-1)3

    =1+(22)3

    =1+66

T₂₃=67
