▶⏩ Let ‘a’ be the any positive integers,
=> then, b= 4.
▶⏩By Euclid's Division lemma:-)
↪➡ a= bm+r. ,, 0≤ r< b. [ m= quotient].
↪➡ a=4m+r. ,, 0≤ r< 4.
→ Hence, possible values of r= 0,1,2,3.
=> Taking r=0.
↪➡ a= 4m+0 → 4m.
=> Taking r=1.
↪➡ a= 4m+1.
=> Taking r=2.
↪➡ a= 4m+2.
=> Taking r=3.
↪➡ a= 4m+3.
▶⏩ Hence, some odd integers are 4m+1 or 4m+3.✅✅
✴✴ Therefore, it is proved that 4m+1 and 4m+3 are positive odd integers for some integers m. ✴✴.✔✔
