Define the type of sequence below. 7, 14, 28, 56, 112, a. neither arithmetic nor geometric b. arithmetic c. both arithmetic and geometric d. geometric

answer is D. geometric

Step-by-step explanation:

7*2=14*2=28*2=56*2=112

Geometric

Step-by-step explanation:

7, 14, 28, 56, 112, ...

To check what type of sequence we compare two consecutive terms

14 divide by 7 is 2

28 divide by 14 is 2

56 divide by 28 is 2

112 divide by 56 is 2

the common ratio of two consecutive number is 2

we have common ratio so the sequence is Geometric

134.6 us dollars

step-by-step explanation:

1 us dollar = 1.33 canadian dollars

so, 150 us dollars = 150 × 1.33 = $199.5.

in canada, the money mitchell spent = 20 canadian dollars.

remaining canadian dollars with him = 199.5 - 20 = 179.5.

after mitchell returned to us, he exchanged the remaining canadian dollars to us dollars.

179.5 canadian dollars = 179.5 × 0.75 = 134.6 us dollars.
