Final answer:
To find the first 5 terms of the arithmetic sequence defined by the equation a_n = 65-100n, substitute the values of n from 1 to 5. The resulting terms are -35, -135, -235, -335, and -435.
Step-by-step explanation:
The given sequence is an = 65-100n.
To find the first 5 terms of this arithmetic sequence, substitute the values of n from 1 to 5.
a1 = 65-100(1)
= -35
a2 = 65-100(2)
= -135
a3 = 65-100(3)
= -235
a4 = 65-100(4)
= -335
a5 = 65-100(5)
= -435
Therefore, the first 5 terms of the arithmetic sequence are -35, -135, -235, -335, and -435.
