Graph the first six terms of a sequence where a1=5 and r=1.25
1 answer:
The sequence above is geometric progression. The nth term of such sequence is given by; Tn = ar∧(n-1), Where a⇒first term and r⇒common ratio So, 1st term = 5×1.25∧(1-1) = 5×1.25∧0 =5 2nd term = 5×1.25∧(2-1) = 5×1.25 = 6.25 3rd term = 5×1.25∧(3-1) = 5×1.25² = 7.8125 4th term = 5×1.25∧(4-1) =5×1.25³ = 9.765625 5th term = 5×1.25∧(5-1) = 5×1.25∧4 = 12.20703125 6th term = 5×1.25∧(6-1) = 5×1.25∧5 = 15.25878909

Since roots go down into the ground, the answers must be negative. That eliminates both 2 4/5 deep and 3.86. You could look at a number line if your unsure, but -3.54 is between 3 and 4, as is -3 2/5.
