progressions

The series of terms a, ar, ar 2 , ar 3 ,.... in which each term bears a constant ratio to the preceeding term is a geometric progression. The constant ratio is called the common rati..

The disturbance produced in the medium travels onward, it being handed over from one particle to the next. Each particle executes the same type of vibration as the preceding one, though not at the same tim..

Let a=first term, d = common difference, l=t n =last term, s = required sum. Then, Writing the series in the reverse order, Adding together the two series, ..

Change in the number of Sarah's friends as she progresses through grades is represented in the line graph. Predict the change in Sarah's friends in grade 6. => increase or decrease or no change or I don′t know..

Kelsey's scores in the first four monthly tests conducted in the school are shown both as a bar graph and as a line graph. Which of these graphs best explains you his progress, and why? => bar graph, because a bar graph compares data or line graph, because a line graph shows changes over ..

M is a point on the rectangle PQRS as shown. The areas a , c and b of triangles PQM, QMR and RMS respectively are in geometric progression. What is the value of S M P M ? => 5 - 1 2 or 3 + 2 2 or 3 - 1 2 or 5 + 1 2..

The sum of n terms of an Arithmetic Progression, S n , is given by the formula S n = n 2 ( a + l ) , where a is the first term and l is the last term of the A.P. Find the first term of the A.P if its last term is 79, and the sum of 9 terms is 396? => 11 or 9 or 8 or 53..

If the roots of the equation a ( b - c ) x ² + b ( c - a ) x + c ( a - b ) = 0 are equal , then write the progression, which the values of a , b , c follow. => AP or AGP or GP or None of these..
