How do i find a37 in an arithmetic sequence of (-12, -5, 2...) ? Also how i do i find the explicit formula for this?

Step-by-step explanation:

Look at the differences between terms.

The initial term is -12, and each successive term is 7 more than the preceding term:

a₂ = a₁ + 7

a₃ = a₂ + 7

Etc.

a₁₃ = a₁ + (13-1)7 = -12 + (12)7 = 72

no, because the sides are not congruent

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7
