Question

find the first five terms of geometric progression a=1024 and r=1/2​

Answer 1

Answer:

GP=1024,512,256,128,64.

Step-by-step explanation:

we know that;

form of GP is a,ar,ar^2,ar^n-1

so,

a=1024

ar=1024×1/2=512

ar^2=1024×1/4=256

ar^3=1024×1/8=128

ar^4=1024×1/16=64

Answer 2

Step-by-step explanation:

• a=1024
• r=1/2

formula is

• tn=at^n-1
• t1=1024×1/2^1-1
• 1024×1/2
• t1=512

• t2=1024×1/2
• t2=512

• t3=1024×1/2×1/2
• t3=256

• t4=1024×1/2×1/2×1/2
• t4=128

• t5=1024×1/2×1/2×1/2×1/2
• t5=24

therefore the first five terms are 512,512,256,128,24
