Observe the patterns and fill in the blanks:
1+11=121+11+111=1231+11+111+1111=___________________1+11+111+1111+11111=_________________________
1234
12345
Hence , required numbers are 1234and 12345 .
In the following, observe the pattern and fill in the blanks.
1x 10 + 1= 111x 100 + 11 = 1111x 1000 + 111= 11111x 10000 + 1111 = 111111 x_____ +______ = 111111
Using the pattern 112 = 121 and 1112 = 12321, we get 11112 =
