​​Observe the following pattern.
​                        1 + 3= 22
                  1 + 3 + 5= 32
            1 + 3 + 5 + 7= 42
And write the value of 1 + 3 + 5 + 7 + 9...... upto n terms.


(How to solve this? Please answer as soon as possible.)
 

Dear student
1+3=22 Here number of terms on LHS=2So, Number of terms×10+2 gives  2×10+2=221+3+5Here number of terms on LHS=3So, Number of terms×10+2 gives  3×10+2=321+3+5+7Here number of terms on LHS=4So, Number of terms×10+2 gives  4×10+2=421+3+5+7+9+.... upto n termsHere number of terms on LHS=nSo, Number of terms×10+2 gives  n×10+2=10n+2
