the first term in a geometric series is 64 and the common ratio is 0.75. find the sum of the first 4 terms in the series

The answer would be 175

Step-by-step explanation:

Step 1, Write the first four terms:

With the number 64, multiply it by 0.75, to get 48. Then multiply 48 by 0.75 again, to get 36. Then multiply 36 by 0.75 to get 27.

Step 2, add up the terms:

The first four terms are 64, 48, 36, and 27. Now just add them together!

64 + 48 + 36 + 27 = 175
