The top number is 4 and t =1, so you need to replace t with 1, find the answer, then replace t with 2 through 4, then find the sum of all of them:
6^1-1 = 6^0 = 1
6^2-1 = 6^1 = 6
6^3-1 - 6^2 = 36
6^4-1 = 6^3 = 216
Sum = 1 + 6 + 36 + 216 = 259
The answer is B.
Answer:
B 259
Step-by-step explanation:
The sum is 4 terms, so we need to add the 4 terms
Term 1: 6 ^ (1-1) = 6^0 = 1
Term 2: 6^ (2-1) = 6^1 = 6
Term 3: 6^ (3-1) = 6^2 = 36
Term 4: 6^ (4-1) = 6^3 =216
The sum is 1+6+36+216 = 259
