Step-by-step explanation:here is the answer

the total savings is 812 rupees in month of Feb

Step-by-step explanation:WE KNOW THAT,

FEBRUARY 2010 IS NOT A LEAP YEAR

, THEREFORE THERE WILL BE 28 DAYS IN THE MONTH OF FEBRUARY

AS PER GIVEN DATA

a=2 , d=2 , n=28

Sn = S28 =?

Sn = n/2 [2a+(n-1)d]

S28 = 28/2 [2×2+(28-1)2]

S28 = 14 [4+27×2]

S28 = 14 [4+54]

S28 = 14 × 58

S28 = 812

ANS :- THE TOTAL SAVINGS IN THE MONTH IF FEBRUARY, 2010 IS ₹812 .
