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

its 69.420

step-by-step explanation:

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
