Write the sum using summation notation, assuming the suggested pattern continues. 16 + 25 + 36 + 49 + + n2 +

Hence, the sum using summation notation, assuming the suggested pattern continues is:

Step-by-step explanation:

We have to write the sum using summation notation, assuming the suggested pattern continues:

Clearly we may also write this pattern as:

So, in terms of the summand it is written as:

( We have started our summation from 4 since the term in the summation starts with 16 which is 4^2 and goes to infinity )
