Answer 2

Answer:

hey mate here is your answer

3. There are 19+12=10 odd numbers here, and the sum is 102 . where N is the last number in the sequence and n is the index of each number in the sequence. So, the 50th number in the sequence is 2⋅50−1=99 , and the sum all the way up to that is (99+12)2=2500 .

4. let the no. be f.

then

45 + f = 14

now here 45 is added here digits will change there places

so,

14 + f = 45

now,

f = 45 - 14

= 31

so , f = 31
