Show that each of the following sequences is an A.P. Also, find the common difference and write 3 more terms in each case. i. 3,\ -1,\ -5,\ -9...... ii. -1,1//4,3//2, 11//4.....

Find the actual lower and upper class limits and also the class marks of the classes : 1.1 - 2.0, 2.1 - 3.0 and 3.1 - 4.0.

Which term of the following sequences:(a) 2,2sqrt(2),4, . . . is 128? (b) sqrt(3),3,3sqrt(3), . . . is 729?(c) 1/3,1/9,1/(27), . . . is 1/(19683)?

Write the first five terms of the sequence and obtain the corresponding series : a_1=3,a_n=3a_(n-1)+2 for all n > 1

Sum to n terms the series 1 + (1+ 2) + (1 + 2 + 3) + (1 + 2 + 3 + 4).......
