Question

The sum of the squares of the first five positive even integers

Answer 1

Answer:

The number series 2, 4, 6, 8, 10. Therefore, 30 is the sum of first 5 even numbers.

Answer 2

Answer:

step 1 Address the formula, input parameters & values.

Input parameters & values:

The number series 2, 4, 6, 8, 10.

The first term a = 2

The common difference d = 2

Total number of terms n = 5

step 2 apply the input parameter values in the AP formula

Sum = n/2 x (a + Tn)

= 5/2 x (2 + 10)

= (5 x 12)/ 2

= 60/2

2 + 4 + 6 + 8 + 10 = 30

Therefore, 30 is the sum of first 5 even numbers.
