Answer:259
Step-by-step explanation:
Its summation of 6^i-1 for values of I = 1,2,3 and 4
= 6^0 + 6^1 +6^2 +6^3
=259
3 because the middle of 2 and 4 is three so three is the midpoint
G^2-4g+6
# Terms: 3, (g^2), (-4g), (6)
Variable: g
Constant: 6
(-4)^2
A negative base raised to an even power gives us a positive so
4^2
4x4=16
