Abu saves N100 000 at 5% compound interest and withdraws #20 000 at the and of each year. What amount is left after 4 years, correct to the nearest kobo?​

6xy and -16xy000000000

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
