What is the value of the problem below?

Hitman42 [59]

Answer:

Step-by-step explanation:

The first term = 6* 2^0 = 6

The second term = 6 * 2^ (2-1) = 6*2 = 12

The third term = 6* 2^(3-1) = 6*2^2 = 6*4 = 24

The fourth term = 6* 2^(4-1) = 6* 2^3 = 6*8 = 48

S4 is the sum of the 1st four terms

S4 = 6+ 12+24+ 48 = 90
