Find the sum of the first six terms of the sequence for which a2=0.7 and a3=0.49.

 Sum of the first six terms is 2.31.

Step-by-step explanation:

Since we have given that

Since we know the formula for "Arithmetic Progression":

Now, solving the above two equations:

So, when we put the value of d in the first equation, we get that

so, Sum of first six terms would be

Hence, Sum of the first six terms is 2.31.

all it means is function 3
