@cuteadi27

1:33:05 The correct ans is 60. therefore between 10 and 250. 60 multiples of 4.😊

@Anonymous_1964

Solutions πŸ‘‡πŸ‘‡


1:33:05 = 60 multiples
1:39:38 = 127 and 133
1:44:06 = a=1 and d=6
1:47:08 = 64
2:26:14 = a = 2 and a13 = 26
2:57:20 = After taking S20 =                 
                  -700 , AP becomes 
                  3,-1,-5,-9.......
3:05:32 = AP = 3,7,11,15.....

@smrxabhinav6277

2:57:34  SIR HERE S20 is 700 u have taken it as 750
and ans is d=-4 and a=3
AP IS 3,-1,-5.............................
