The explicit formula for the nth term of an arithmetic sequence is an=a1+(n-1)*d. What is the simple formula corresponding to the explicit formula if the first term of the sequence is -10 and the difference between terms in the sequence is 5?

Respuesta :

[tex]T_n = a_1 + d(n-1)[/tex]

Given that first term = -10 and the difference is 5

[tex]T_n = -10 + 5(n - 1)[/tex]

[tex]T_n = -10 + 5n - 5[/tex]

[tex]T_n = 5n - 15[/tex]
