What is the first 6 terms of this geometric sequence? 1, 8, 64, 512,
a. 1024
b. 4096
c. 32768
d. 37449

is D. 37449

Step-by-step explanation:

Use the formula. Sn=a1(1−r^n) / 1−r, Where a1 is the first term (1 in this case), r is 8, and n is the number of terms. So (n)=1(1-8^6)/(1-8)=37449

i can't see the picture : /

3 4 7 12 19

+1 +3 +5 +6

i would guess 26 because this isnt a sequential pattern or its to short to know
