Answer:
Its the first choice.
Step-by-step explanation:
an = the nth term. so:
a1 = 6(1) + 1 = 7
a2 = 6(2) + 1 = 13
a3 = 6(3) + 1 = 19
The common difference is 6.
18.432 + 5.55 + 19.3
We can notice that the last number in the process of addition is 19.3 | with 1 decimal place value / 3 significant figures |
It is better to change all values to 1 decimal place value / 3 significant figures
18.432 → 18.4
5.55 → 5.6 ( 5 rounds up )
19.3 → 19.3
Let us add:
18.4 + 5.6 + 19.3 = 43.3
If you add the original numbers, you will get
18.432 + 5.55 + 19.3 = 43.282
43.282 ≈ 43.3
