Question

111+111=6
121+121=8
131+131=10
151+151=?

Answer 1

We need to find the pattern here.

The pattern should be same in all the sequences. In this case 1+1+1+1+1+1 is 6.

Then 1+2+1+1+2+1 comes to 8.

Then 1+3+1+1+3+1 comes to 10.

Now we know the pattern, so the answer comes to 1 + 5 + 1 + 1 + 5 + 1  becomes 14

Answer 2

Solution :-

There is a certain pattern in he given series. If you see it carefully then you will find it. This is as follows.

111 + 111 = 6 ⇒ 1 + 1 + 1 + 1 + 1 + 1 = 6

121 + 121 = 8 ⇒ 1 + 2 + 1 + 1 + 2 + 1 = 8

131 + 131 = 10 ⇒ 1 + 3 + 1 + 1 + 3 + 1 = 10

151 + 151 = 14 ⇒ 1 + 5 + 1 + 1 + 5 + 1 = 14

So, the correct answer is 14
