WRITING number on the right. -2x = 6 What is the next term of this sequence? 22, 15, 8, 1, . How many centimetres are there in 900mm in regards to length? Write an equation for the nth term of the geometric sequence. r = a2/a1 Question 41. f(t) = 5(4)t an = -2(9)^(n-1). The equation of the line is y = mx + c V = s Question 12. Write a recursive rule and an explicit rule for the sequence. = 3 (-4) = 7 . Fill in the exponent of x with a number to simplify the expression. 2x 3x = -1 4 You begin observing the number of bacteria 3 hours after the culture is prepared. V = 1/6(1.77)S3 / 2 a6 = 375 r6-1 We can remember the greater than symbol using this method. d. Part (a) involves a geometric sequence with a common ratio of 2. a6 = 656.1 9 = 5904.9 r^(n-1) So you have 7/100 here.
