In a sequence of numbers, each number is 7 less than 3 times the previous number. For example, if the first number is five, the second number would be 8 (3 x 5 - 7) and the third number would be 17 (3 x 8 - 7). If the third number in the sequence was 53, what was the first number in the sequence?

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
