answer: sn= 2480

step-by-step explanation:

sn= a1 (1-r^n) / 1-r

so first, the formula tells us exactly where to put all our given numbers.

s5= 80 (1-2^5) /1-2

now let's start from the parenthesis which consists:

(1-2^5)

times the number 2 with exactly how many the power is.

2×2×2×2×2 = 32

next is minus 1 and 32:

s5= 80 (1-32) / 1-2

s5= 80 (-31) / 1-2

next is to minus the 1 and 2. the ones at the end:

s5= 80 (-31) / -1

next is to multiply the a1 and the one inside the parenthesis:

s5= -2480 / -1

and finally, divide them. also, the signs in both sides are negative. in divition, if both signs are the same then automatically, the answer should be positive.

s5= 2480
