Answer:
7
Step-by-step explanation:
Formula of a Geometric Sequence :
aₙ = arⁿ⁻¹
============================================================
Given :
⇒ a = 7
⇒ r = -1
⇒ n = 101
==========================================================
Solving :
⇒ a₁₀₁ = ar¹⁰⁰
⇒ a₁₀₁ = (7)(-1)¹⁰⁰
⇒ a₁₀₁ = 7(1)
⇒ a₁₀₁ = 7
Term
The rule for a number pattern is: Multiply each term by -1. If the 1st term is 7, what will be the 101st term.
- 101 = ar¹⁰⁰
- 101 = (7)(-1)¹⁰⁰
- 101 = (7)1
- 101 = 7
so the 101st term is 7.
