Question

what is tn for even natural number

Answer 1

natural numbers?
We need to compute 22 + 42 + 62 + …. + (2n)2

EvenSum = 22 + 42 + 62 + .... + (2n)2
= 4 x (12 + 22 + 32 + .... + (n)2)
= 4n(n+1)(2n+1)/6
= 2n(n+1)(2n+1)/3

Answer 2

Answer:

tn for even natural number will be t₂n

Step-by-step explanation:

as any natural number may it be odd or even when multiplied by 2 gives even natural number.

for eg- let 'n' be an odd  number 3, hence 3×2=6.

         - let 'n' be an even number 8,so 8×2=16    

           in the above examples the products,16 and 6 are even natural                    

           numbers
