Sagot :
To determine the value of [tex]\( a_{10} \)[/tex] for the sequence defined by [tex]\( a_n = 3n - 5 \)[/tex], we need to substitute [tex]\( n \)[/tex] with 10 in the formula.
1. Start with the sequence formula:
[tex]\[ a_n = 3n - 5 \][/tex]
2. Substitute [tex]\( n = 10 \)[/tex] into the formula:
[tex]\[ a_{10} = 3(10) - 5 \][/tex]
3. Perform the multiplication:
[tex]\[ 3 \times 10 = 30 \][/tex]
4. Subtract 5 from the result of the multiplication:
[tex]\[ 30 - 5 = 25 \][/tex]
Thus, the value of [tex]\( a_{10} \)[/tex] is:
[tex]\[ \boxed{25} \][/tex]
