Question

The sum of 33 consecutive even numbers is 78.

Answer 1

Answer:

data is wrong

Step-by-step explanation:

n = 33

d = 2 as consecutive even terms

last term = a + (33-1)*2

= a + 64

Sum = (n/2)(a + Last Term)

= (33/2)(a + a +64)

= (33/2)*(2a+64)

= 33a + 1056

33a + 1056 = 78

a = -978/33

a = - 29.63  ( its not an even number)

so data is wrong

if a = -30 then sum = 66 for 33 terms

if a = -28 then sum = 132 for 33 terms
