How do you day 1: 45min day 2: 45 x 2= 90 min day 3: 90 x 2= 180 min day 4: 180 x 2 = 360 min day 5: 360 x 2 = 720 min day 6: 720 x 2 = 1440 min day 7: 1440 x 2 = 2880 min in sequence notation

7

∑ 45 2^(k-1)

k=1

Step-by-step explanation:

We are multiplying by 2 each time

The 1st term of the sequence is 45

45 *2 ^(k-1)

a1 =45

a2 = 45* 2^(1) = 45*2 = 90

a3 = 45* 2^2 = 45*4 =180

a4 = 45* 2^3 = 45*8 =360

∑ 45 2^(k-1)

k=1

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19
