2601.5

ans can be calculated as: 1272 + 1272 + d(n/2)

where d= difference between the consecutive terms i.e given constant
and n= no. of terms i.e. given 46

6. ## Re: F! Contest - Master-Mind of the DAY: Day 9

Ans is 2544+23d...... d being the common difference of the arithmetic progression

7. ## Re: F! Contest - Master-Mind of the DAY: Day 9

Is there any answer for this question???

8. ## Re: F! Contest - Master-Mind of the DAY: Day 9

SOLUTION NO-1 =46/2(P1+P46)
=23(P1+P46)

SOLUTION NO-2 =46/2{ 2(P1)+(46-1)(CONSTANT DIFFERENCE TERM)}
23 { 2(P1) + (46-1)(CD) }
where CD is CONSTANT DIFFERENCE TERM

10. ## Re: F! Contest - Master-Mind of the DAY: Day 9

Solution is =2544
by arithematic progression

11. ## Re: F! Contest - Master-Mind of the DAY: Day 9

answer is 2544+d where d is constant difference between the consecutive terms
