Step-by-step explanation:

if you replace n = 1

(2)(7)^(1-1)

= (2)(7⁰)

= 2×1

= 2

if n = 2

(2)(7)^(2-1)

= (2)(7)^(1)

= 2×7

= 14

choice 1

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

don't know what that says sorry i can't you
