1.
17+1 x 1/2 =9
9+1 x 2/2 = 10

2.
*1+7*1
*2+6*2
*3+5*3

3.
(x/2) - 1 

4.
x3+1
x3+2
x3+3...

5.
x7+1
x6+2
x5+3...


1.
17*0.5 +0.5=9
9*1 +1=10
10*1.5 +1.5=16.5.....and so on...so ans is 10.

2.6*1+7=13 , 13*2+12=38 , 38*3+15=129 , 129*4+16=532 , 532*5+15=2675...
here the added no.s 7,12,15,16 &15 have differences 5,3,1&-1 respctvly..which themslvs have difference = 2.

14.
2*22/7*r=2(26+18)...r=14....
Area=2*22/7*14^2=616 sqcm..

  1. 2pi*r=2(l+b)
    Pi*r=l+b
    pi*r=18+26

    pi*r=44

    r=44*7/22

    r=14

    pi*r^2 =22/7 *14* 14 =616
