Question number 27 me Positive integer ki baat hui hai to 3 ko kaise likh sakte hai jabki 0 positive integer me count nhi hote... To frst term 3 nhi likh sakte.. Ans 13 hoga. series 10 se strt kro.
@@letslearnmathsin4074 for 2n terms, last term (l) = a+(2n-1)d = 2+(2n-1)×3 = (6n-1) For n terms, last term (l) = a+(n-1)d = 57+(n-1)×2 = (2n+55) now the sum is equal so, 2n/2 [ a+l ] = n/2 [ a+l ] => 2n/2 [ 2+6n-1] = n/2 [ 57+2n+55 ] Therefore, n = 11 (ans) Do the calculation.

Kaise kiya 30 ka plz explain
@@letslearnmathsin4074 for 2n terms,
last term (l) = a+(2n-1)d = 2+(2n-1)×3 = (6n-1)
For n terms,
last term (l) = a+(n-1)d = 57+(n-1)×2 = (2n+55)
now the sum is equal so,
2n/2 [ a+l ] = n/2 [ a+l ]
=> 2n/2 [ 2+6n-1] = n/2 [ 57+2n+55 ]
Therefore, n = 11 (ans)
Do the calculation.
