Answer:
Address the formula, input parameters & values.
Input parameters & values:
The number series 2, 4, 6, 8, 10, 12, 14.
The first term a = 2
The common difference d = 2
Total number of terms n = 7
step 2 apply the input parameter values in the AP formula
Sum = n/2 x (a + Tn)
= 7/2 x (2 + 14)
= (7 x 16)/ 2
= 112/2
2 + 4 + 6 + 8 + 10 + 12 + 14 = 56
Therefore, 56 is the sum of first 7 even numbers.
