A. 56 B. 58 C. 60 D. 62 E. 64 The number of consecutive even integers is $$\frac{the \ last \ term(L) – the \ first \ term(F)}{2} + 1$$ and its range is $$L-F$$. Now, $$\frac{Range}{2} + 1 = \frac{(L-F)}{2} + 1 = 29$$. So, $$\frac{Range}{2} = 28$$, and, hence, $$Range = 56$$.

Another way....

How many gaps are there in 29 consecutive even integers -28
As there is 1 gap in two numbers ...x_y
Two gaps in 3 numbers x_y_z
So 28 gaps in 29 numbers and each gap is 2 units..
So total 28*2=56

A

Let's consider the first 29 even numbers,

2,4,6......

2(1,2,....29)

First even number = 2
Last even number of the 29 numbers = 2*29
= 58

Range = Max - Min
= 58 - 2
= 56

So, Option A is correct
