Question

the sum sum of 6 consecutive even numbers is 270. what is the second number in this sequence

Answer 1

Answer:

42

Step-by-step explanation:

first term = a

sixth term = a + (6-1)d

d =2 as even number

sixth term = a + 5*2 = a + 10

Sum = (n/2)(first term + last Term)

270 = (6/2)(a + a +10)

270 = 3 (2a +10)

90 = 2a + 10

80 = 2a

a = 40

second term = 40 + 2 = 42
