Answer 2

Looks like it's just subtracting 5...

Answer 3

So subtract 5 to get the second, then do it again to get the third

Answer 4

oh

Answer 5

haha well i have another question, so i'll post it

Answer 6

This looks arithmetic, a_n = a_1 + d(n – 1)

a_4 = -7 -5(4 – 1)
a_4 = -7 -5(3)
a_4 = -7 -15
a_4 = -22 <-- checking (/)_(\)

a_5 = -7 -5(4)
a_5 = -7 -20
a_5 = -27




So just put a_2 = -7 -5(2-1)
a_2 = -7 -5(1)
a_2 = -7 -5
a_2 = -12
