Inclusive means including 1 and 80
ok so we know that 1^2=1 so 1 is a perfect square
just go up and square them untill 80 and the results is your answers
2^2=4, 4 is another
3^3=9
4^2=16
5^2=25
6^2=36
7^2=49
8^2=64
9^2=81 which is over
so the perfect squares from 1 to 80 are
1,4,9,16,25,36,49,64
The first term is 2 and the common ratio = -8/2 = -4
S7 = 2 * (-4)^7 - 1
------------- = 6554 answer
