Answer:
a)112 and 113
b)180 and 181
c)144 and 145
d)84 and 85
Step-by-step explanation:
Let the consecutive no.be x and x+1
a)x+(x+1)=225
2x+1=225
2x=225-1
2x=224
x=224/2
x=112
therefore,
x=112
x+1=112+1=113
Hence, the consecutive no. are 112 and 113
b)x+(x+1)=361
2x+1=361
2x=361-1
2x=360
x=360/2
x=180
therefore,
x=180
x+1=180+1=181
Hence, the consecutive no are 180 and 181
c)x+(x+1)=289
2x+1=289
2x=289-1
2x=288
x=288/2
x=144
therefore,
x=144
x+1=144+1=145
Hence, the consecutive no are 144 and 145
d)x+(x+1)
2x+1=169
2x=169-1
2x=168
x=168/2
x=84
therefore,
x=84
x+1=84+1=85
Hence, the consecutive no are 84 and 85
