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
