Question

The sum of 7 consecutive integer is 91 then the sum of first two terms is

Answer 1

Answer:

21

Step-by-step explanation:

Let a be the first term.

Then the 7 consecutive numbers are

a, a+1, a+2, a+3, a+4, a+5, a+6

Their sum is

a + a+1 + a+2 + a+3 + a+4 + a+5 + a+6 = 91

=> 7a + 21 = 91

=> 7a = 70

=> a = 10

So the first two terms are 10 and 11.

The sum of the first two terms is then 10+11 = 21.
