Answer 1

STEP 1 :- Address the formula, input parameters & values.

Input parameters & values :- The number series 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, . . . . , 360.

STEP 2 :- Apply the input parameter values in the AP formula.

Sum = n/2 x (a + Tn)

= 60/2 x (6 + 360)

= (60 x 366)/ 2

= 21960/26 + 12 + 18 + 24 + 30 + 36 + 42 + 48 + 54 + 60 + . . . . + 360 = 10980

ANSWER :- Therefore, 10980 is the sum of first 60 positive integers which are divisible by 6.
