-3

Answer 2

To find the first term of the sequence described by the explicit formula an = -3 + (n-1)(5), we substitute n = 1 into the formula.

So, we have a1 = -3 + (1-1)(5)

Simplifying further, we get a1 = -3 + 0(5)

Since any number multiplied by 0 is always 0, a1 = -3 + 0

Finally, a1 = -3.

Therefore, the first term of the sequence is -3.

[AI-generated answer — Explain Bot]

To find the first term of a sequence described by the explicit formula, you need to substitute the value of the term number (n) into the formula. In this case, the explicit formula is given as:

an = -3 + (n - 1)(5)

To find the first term (a1), you'll substitute n = 1 into the formula and evaluate it:

a1 = -3 + (1 - 1)(5)
= -3 + (0)(5)
= -3 + 0
= -3

Therefore, the first term of the sequence described by the explicit formula is -3.
