The nth term of a sequence is n+7
work out the first three terms

Term 1

Substitute 1 into N

(1) + 7 =8

Term 2

Substitute 2 into N

(2) + 7  =9

Term 3

Substitute 3 into N

(3) + 7 = 10

Step-by-step explanation:

hello : put this values n=1  , n=2  ;n=3

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
