Then you'll need to get started on it pretty soon.
Just take it slow and easy, and remember your order of operations (or PEMDAS).
First look through it and do any multiplications and divisions that you find.
Then do the additions and subtractions.
I just gave it a quick scan and I came up with 26. I dont know if it's correct.
Get to work. You can do this !

Find the sum of the following geometric sequences. d) 3 terms a= 16 r=3/4

kodGreya [7K]

Answer:

S₃ = 37

Step-by-step explanation:

given a₁ = 16 and r = $\frac{3}{4}$ , then

a₂ = a₁ × $\frac{3}{4}$ = 16 × $\frac{3}{4}$ = 12

a₃ = a₂ × $\frac{3}{4}$ = 12 × $\frac{3}{4}$ = 9

then

S₃ = a₁ + a₂ + a₃ = 16 + 12 + 9 = 37
