Answer:
represents a particular any term and
represents just previous term.
![a_8=38](https://tex.z-dn.net/?f=a_8%3D38)
Step-by-step explanation:
In the given recursive formula,
![a_n= a_{n-1}+5](https://tex.z-dn.net/?f=a_n%3D%20a_%7Bn-1%7D%2B5)
represents ![n^{th} \ term](https://tex.z-dn.net/?f=n%5E%7Bth%7D%20%5C%20term)
and
represents just its previous term.
To find
, first five terms are given there. We need to find its previous terms ![a_6 \ and\ a_7](https://tex.z-dn.net/?f=a_6%20%5C%20and%5C%20a_7)
![a_6 = a_{n-1}+5\\a_6= a_{6-1}+5\\a_6 = a_5 +5\\substitute \ a_5 =23\\a_6 = 23+5=28](https://tex.z-dn.net/?f=a_6%20%3D%20a_%7Bn-1%7D%2B5%5C%5Ca_6%3D%20a_%7B6-1%7D%2B5%5C%5Ca_6%20%3D%20a_5%20%2B5%5C%5Csubstitute%20%5C%20a_5%20%3D23%5C%5Ca_6%20%3D%2023%2B5%3D28)
Similarly,
![a_7 = a_{n-1}+5\\a_7= a_{7-1}+5\\a_7 = a_6 +5\\substitute \ a_6 =28\\a_7 = 28+5=33](https://tex.z-dn.net/?f=a_7%20%3D%20a_%7Bn-1%7D%2B5%5C%5Ca_7%3D%20a_%7B7-1%7D%2B5%5C%5Ca_7%20%3D%20a_6%20%2B5%5C%5Csubstitute%20%5C%20a_6%20%3D28%5C%5Ca_7%20%3D%2028%2B5%3D33)
Similarly,
![a_8 = a_{8-1}+5\\a_8= a_{8-1}+5\\a_8 = a_7 +5\\substitute \ a_7 =33\\a_8 = 33+5=38](https://tex.z-dn.net/?f=a_8%20%3D%20a_%7B8-1%7D%2B5%5C%5Ca_8%3D%20a_%7B8-1%7D%2B5%5C%5Ca_8%20%3D%20a_7%20%2B5%5C%5Csubstitute%20%5C%20a_7%20%3D33%5C%5Ca_8%20%3D%2033%2B5%3D38)
Thus
is the answer.
