Question

solve each problem by looking for a pattern. 1. measurement what is the perimeter of the twelfth figure? figure 1 perimeter = 6 figure 2 perimeter = 8 figure 3 perimeter = 10

Explanation:

Step1: Identify perimeter pattern

Perimeters: 6 (Fig1), 8 (Fig2), 10 (Fig3); increases by 2.

Step2: Define arithmetic sequence

a₁=6, d=2, n=12. Formula: aₙ=a₁+(n-1)d.

Step3: Calculate 12th term

a₁₂=6+(12-1)*2=6+22=28.

Answer:

28
